Make Potassium Permanganate (sort of...) We make potassium permanganate from the potassium nitrate and manganese dioxide we obtained in previous videos. Warning: This experiment deals with very high temperatures in glass equipment. Face shields and protection against shattering glass is required. In addition small quantities of toxic gases are produced. This experiment should be performed outside or in a fume hood. Make a vial with a mixture of 7 grams of potassium nitrate and 1 gram of manganese dioxide. Using a torch carefully heat the mixture so they melt together. Smoke and fumes should be liberated as the potassium nitrate oxidizes any contaminants in the manganese dioxide. Keep the mixture molten for a few minutes. Now add 2 grams of potassium hydroxide and heat the mixture again thoroughly. It will boil and turn green as the reactants generate potassium manganate. Keep it on a gentle boil for several minutes. Let the vial cool and then smash it apart with a hammer. Obtain the green solid and pulverize it into a powder. Mix this powder with 50 mL of water and dissolve the green potassium manganate. Let it settle and then pour off the solution. The solution can be converted to potassium permanganate by adding drops of either sulfuric acid or sodium bicarbonate. Just keep adding and stirring until the solution turns purple. If you go too far it will turn light pink indicating the permanganate has been destroyed. Let the byproduct of brown manganese dioxide settle out and the liquid is a weak solution of ...
Low Potassium Warning!! My potassium levels are too low and it's scared me.
How to Make Potassium Nitrate at Home How to make potassium nitrate at home with instant cold packs and "sodium-free" salt. "Sodium-free" salt is actually potassium chloride. Instant cold packs contain ammonium nitrate and if the two are mixed potassium nitrate and ammonium chloride are formed in equilibrium. Fortunately potassium nitrate has lower solubility than ammonium chloride at colder temperatures giving us a means of separation. Just mix 40 grams of ammonium nitrate with 100mL of water and stir until dissolved. Filter the mixture directly into 37 grams of potassium chloride. Gently heat until completely dissolved, do not boil. Cool the mixture to 0 Celsius in the freezer or on an ice bath. Filter the crystals and dry them. Now you have potassium nitrate. To test it mix 2 parts potassium nitrate with one part sugar and light it up. It should burn with a purple/pinkish flame.

KCLO4(Potassium Perchlorate) Sodium Chloride is electrolysized to render Sodium Perchlorate in a single run. A rewound "MOT" is used with a pi filter for the power supply. Power supply quality is checked under load with an oscilliscope. DC ripple is less than 1/10 volt. The electrolysis voltage is kept above 6 volts and the current is maintained at 25 amps. Total run time was 180 hours. Solution temp was 85-90C. Electrolyte consisted of 1140g of sodium chloride (table salt) dissolved in 4L of distilled water. All of the electrolyte was run through the 3L cell over the course of 7 1/2 days. At 144hours run time, a test for perchlorate was done using Methylene blue. A strong presence of perchlorate was indicated by violet color. The cell run continued for an additional 36 hours. The electrolyte was hot filtered to remove the white flock that accumulated on the bottom of the cell and then boiled in a beaker for 45 minutes. The 3L solution was divided in half. 1500mL of electrolyte and a boiling 2 liter solution containing 2 lbs. of KCL were combined in a 5 liter beaker. This metathesis mixture was left to cool to room temp and then cooled in a refrigerator. The accumulated crystals were filtered and thoroughly washed with distilled water. The yield was approximately 980g. Another test with methylene blue on the result strongly indicated perchlorate.
Potassium bicarbonate lowered my blood pressure nearly 20 points to 121/72 mm Hg Hi this is Larry Hobbs @ . Potassium bicarbonate lowered my blood pressure nearly 20 points to 121/72 mm Hg. I believe potassium bicarbonate is superior to potassium chloride because we used to consume more potassium (3-4 times more), more bicarbonate, and less sodium (3-10 times less) and less chloride as has been noted by researchers from the University of California, San Francisco who have been studying this for 15 years or more. Potassium bicarbonate has been shown to - reduce bone loss - reduce muscle loss - attenuate the reduction in growth hormone that occurs with age - reduce kidney stone formation Citrate is a precursor to bicarbonate in the body, so potassium citrate found in food is converted in the the acid-neutralizing bicarbonate in the body. The researchers argue that our diet is mismatched with our genes, and that we suffer from a low-grade, diet-induced, metabolic acidosis that may be causing many of the age-related health problems that occur.

Make Potassium Chlorate from Bleach How to Make Potassium Chlorate from Bleach and sodium-free salt. Warning: This produces small amounts of chlorine gas, this should be done outside or in a fumehood. Potassium chlorate is a useful oxidizer and small amounts can be easily made using household chemicals. Start by boiling a large quantity of household laundry bleach, at least half a liter, until crystals start to precipitate. Immediately take it off heating and let it cool. As it cools make a saturated solution of potassium chloride. Potassium chloride is sold as a "sodium-free" salt substitute. Now once the bleach is cooled, measure out an equal volume of potassium chloride solution and pour into the boiled bleach solution but do not mix in the crystals. Stir up the mixture and eventually potassium chlorate crystals will precipitate out. What's happening is the sodium hypochlorite in the bleach is disproportionating to form sodium chloride and sodium chlorate. Adding the potassium chloride exchanges the ions and precipitates out potassium chlorate. The boiling is required for this reaction to work; you can't simply let the bleach evaporate.
Dr. Ben Fuchs: Potassium Iodide is A Must for Nuclear Disaster in Japan 1/2
Make Potassium Iodide If you want to read about this video and how it relates to the recent concerns about radiation in Japan, see the following post on my blog: Here I make potassium iodide from elemental iodine and potassium hydroxide. 3I2 + 6KOH == 5KI + KIO3 + 3H2O The coproduct of potassium iodate can be separated easily because it is far less soluble in water, and to ensure it was all precipitated out I immersed the solution in an ice bath. This video is a good demonstration of how things really go when you do chemistry yourself. You start with a bunch of assumptions, and a lot of the time many of these are proven wrong and you have to figure out another way to do it. For example, the additional heating I had to do and the fact that I used too much iodine. I've added a number of annotations to highlight this as well.

Where to buy Potassium Nitrate (Spectracide Stump Remover) *edit* Spectracide Stump Remover now comes in a black bottle with a black lid, however, the shape remains the same. READ THE FOLLOWING BEFORE WATCHING: This is a video response to the "How To Make Explosive White Powder" video. In this video, your questions will be answered about where to get various chemicals. Seriously guys, no more questions about "where do i buy potassium nitrate" or "where do i but stump remover". Watch this to find out where to buy it, and shut up. Read the comments before you post, or even try using the nice search engine called "Google". One more thing: Saltpeter (saltpetre) IS Potassium Nitrate. It can also be sodium nitrate, but that's not much of a difference. Sodium Nitrate and Potassium Nitrate are virtually the same.
Synthesis of sodium bromated and potassium metaperiodate In this experiment I will show how it is possible to make sodium bromated and potassium metaperiodate. Sodium bromated: First you need to make a saturated solution of sodium bromide. To this then add a small amount (just a pinch) of potassium dichromate. The dichromate stops the reduction of the bromated ion when the solution becomes concentrated with them. Then make the circuit as see in the video. You need a 3~5 ohm resistor to reduce the current. I found that a coil of wire works well. It also has the advantage on not overheating like a smaller component would. The electrodes were carbon ones from a battery. For more information on getting rods and chemicals out of batteries look at NerdRages great vid. Then let the cell run for about 6 hours. With periodic string and adding more water if any evaporates. After this time put it in an ice bath then filter and wash the crystals. Improvements:- use platinum electrodes instead of carbon and the biggest one of all use potassium bromide instead of sodium. The crystallisation will be easier. Over all I got approximately a 15% yield which is pretty bad. The final product was quite impure but it did work. Potassium metaperiodate: First dissolve 4g of potassium iodate and 7g of potassium hydroxide in 20ml of water. Then heat the beaker up to just simmering. Then set up the chloride generator by mixing (small amounts!) of potassium permanganate and hydrochloric acid. The gas given off is chlorine. Bubble this gas ...

Potassium and Water A reaction of small piece of potassium metal with water. The flame you see is actually burning hydrogen given off but is colored pink due to potassium vapor.
Elementary Productions: Potassium Iodide and Lead Nitrate A petri dish is filled with a small amount of water. Potassium Iodide is added to the petri dish in one end, and Lead Nitrate in the other end. As the two salts diffuse, Lead Iodide is precipitated as a "barrier" surrounding the place where the Lead Nitrate was placed. This is because of a substance with a high molecular weight diffuses more slowly than a substance with a lower molecular weight. This rule applies for any medium used, in this case water. Another good example of diffusion is why flatulence is able to smell up a room in seconds. Hydrogen sulfide (the substance responsible for the smell) has a pretty low molecular weight, and therefore diffuses faster. This experiment serves as a good demonstration on diffusion, because of the difference in molecular weights, the insolubility of Lead Iodide in water, and the color of the precipitate.

Make Sodium Nitrate, A Potassium Nitrate Substitute How to make sodium nitrate, which can substitute for potassium nitrate in almost all pyrotechnic purposes except flame color. Note: Sodium Nitrate is somewhat hygroscopic. Stuff you make from it such as pyrotechnic compositions should be used soon after making and not stored for extended periods of time. WARNING: Both procedures produce large quantities of ammonia gas. You have to do this experiment outside or in a fumehood. First get ammonium nitrate from an instant cold pack as seen in our previous video: For the baking soda method. Get 80 grams of ammonium nitrate and dissolve it in 150mL of water. Filter it off directly into 84 grams of sodium bicarbonate, which is baking soda. Don't expect it to dissolve, it won't. Boil the mixture down to 100mL or less. This is needed to decompose the ammonium bicarbonate that's formed. You cannot simply evaporate the mixture. The boiling will release large amounts of ammonia so you have to do this outside or in a fumehood. Once it's boiled, leave it to evaporate until dry. Sodium nitrate will decompose if heated too strongly so you cannot boil it down all the way dry unless you can ensure the temperature never goes above 200 Celsius. Leaving a little water is the safest way to ensure the best product. For the sodium hydroxide method: Place 80 grams of ammonium nitrate in a tall container and pour 40 grams of sodium hydroxide on top. Then carefully pour 30mL of water and stand back. It will quickly react to generate ...

What Is Potassium What Is Potassium Name Origin From potash (pot ash); K from latin: kalium "Potassium" in different languages. Sources Found in minerals like carnallite [(KMgCl3).6H2O] and sylvite (KCl). Potassium makes up about 2.40% of the weight of the Earth's crust, it is the seventh most abundant element. The main sources of potash are mined in USA (California, New Mexico and Utah) and Germany. Around 200 tons are produced annually. Abundance Universe: 3 ppm (by weight) Sun: 4 ppm (by weight) Carbonaceous meteorite: 710 ppm Earth's Crust: 15000 ppm Human: 2 x 106 ppb by weight 3.2 x 105 ppb by atoms Uses Used as potash (potassium carbonate) in making glass, soap, lenses and salt substitute. Also as potassium nitrate (KNO3, also called saltpeter) it is used to make explosives and to colour fireworks in mauve. Glass treated with liquid potassium is much stronger than regular glass. Potassium chloride (KCl) is used as a substitute for table salt and is also used to stop the heart, eg in cardiac surgery and in executions by lethal injection in solution. History Potassium was discovered in 1807 by Sir Humphry Davy, who derived it from caustic potash (KOH). Potassium was the first metal that was isolated by electrolysis.

How To Make Potassium Nitrate Make Potassium Nitrate from Instant Cold Packs and Potassium Hydroxide Warning: This reaction will produce large quantities of toxic ammonia gas. Perform the reaction outside or in a fume hood. Potassium hydroxide is highly corrosive; wear gloves when working with it. Also note that this video is for those interested in the chemistry, it's not cheaper/better/easier than buying it. Some instant cold packs contain ammonium nitrate as their active ingredient and when mixed with potassium hydroxide will produce potassium nitrate and ammonia gas. Get an instant cold pack that clearly says it contains ammonium nitrate, cut it open, and pour the contents into a container. If its unused there will be a water pouch that you can discard. The rest of the pack is ammonium nitrate. Usually its coated in an anti-caking agent so it'll be off-color. If you're using an already used instant cold pack then filter out the liquid and let it evaporate until it's dry. The crystals will be ammonium nitrate. Take 80 grams of ammonium nitrate and dissolve in 70 milliliters of hot water. This will take some time so be patient. It will take even longer in cold water so use hot water when you can. If it has an insoluble anti-caking agent then you need to filter it off through a coffee filter. Separately, measure out 56 grams of potassium hydroxide. Potassium hydroxide is sold online to make homemade soaps and for biodiesel. Add just enough water to completely dissolve the potassium hydroxide. When ...

KI Tablets potassium iodide Radiation Pills nuclear radiation Fallout Protection Do you have your radiation pills? What is the big deal about Potassium Iodate (KIO3) or Potassium Iodide (KI)? You know it is for nuclear preparedness, but just why is it so important? Of all the radioactive isotopes and radioactive particles that can come from a nuclear reaction, radioactive iodine 131 (I-131) poisoning is one of the most lethal. The good news is that damage to the thyroid from exposure to I-131 can be prevented. Keep in mind these facts about your thyroid: 1) Your thyroid runs on iodine. 2) Your thyroid is a pig. 3) Your thyroid is stupid. Your thyroid runs on iodine and will absorb all it can until it is absolutely full. This fullness is called saturation or blockade. However, your thyroid does not know the difference between good iodine and bad iodine. Good iodine is taken up by the thyroid in the form of potassium iodate (KI03) or potassium iodide (KI). Bad iodine, I-131, is a radioisotope of iodine which is produced in nuclear reactions such as a bomb or nuclear power plant. I-131 is what we call a beta emitter and if you get it on your skin it will burn you in much the same way as when you get bad sunburn. It has a half-life of roughly 8 days (8.01 to 8.07). One of the reasons spent fuel rods are stored in pools of water for months at a time, is that they will be off-gassing I-131 for roughly 10 half-lives (approximately 80 days). If you are caught unprotected and downwind from a nuclear reaction and the plume or cloud of ...
