Reduction of Copper Oxide Reduction of Copper Oxide Black copper oxide and black carbon powder are mixed together and heated up. The gas evolved is passed into a solution of calcium hydroxide (lime water), a white precipitate of calcium carbonate is formed as the gas passes through the lime water. This shows that carbon dioxide is being produced. As the mixture is heated, the copper oxide is reduced to red copper by the carbon. After the mixture is cooled, you can now see it is red-brown due to the copper produced by the reduction. Video from:
Limewater & CO2 Carbon dioxide dissolves in water to form carbonic acid (H2CO3). Lime water is a solution of calcium hydroxide (Ca(OH)2). They react to form calcium carbonate (CaCO3) and water. Calcium carbonate is insoluble and forms a white precipitate. If CO2 continues to be passed,more carbonic acid forms, which then reacts with with the calcium carbonate to form calcium hydrogencarbonate, which is soluble, so the precipitate is seen to dissolve..

The Poppin' Fresh Experiment 3 ... kinda This is the worst one yet... Poppin' Fresh now drinks his own urine... No, not really, it's just Pepsi Max and Lemon & Lime water mixed together, so please do NOT try and drink your urine. Feel free to drink Pepsi Max and Lemon Lime water, together or apart though, they're pretty good.

Candle Burning Combustion reaction of a candle burning. C27H56 + 41O2 = 27CO2 + 28H2O candle plus oxygen forms carbon dioxide and water. I also show limewater Ca(OH)2 as an indicator for CO2 and cobalt II chloride CoCl2 as an indicator for the presence of water. dupuis.shawbiz.ca

CaO Experiment conducted at home CaO can be easily found in packed dried food, or dehumidifying bags. 1. CaO (s) + H2O (l) → Ca(OH)2 (s) + heat 2. Ca(OH)2 (s) + H2O (l) —filtrate→ Ca(OH)2 (aq) [lime water, colourless] 3. Ca(OH)2 (aq) + CO2 (g) → CaCO3 (aq) [milky] i) CO2 (g) + H2O (l) → H2CO3 (aq) [carbonic acid] ii) H2CO3 (aq) + Ca(OH)2 → CaCO3 (aq) [milky] 4. CaCO3 (aq) + CO2 (g) + H2O (l) → Ca(HCO3)2 (aq) [colourless] i) CO2 (G) + H2O (l) → H2CO3 (aq) [carbonic acid] ii) H2CO3(aq) + CaCO3 (aq) → Ca(HCO3)2 (aq) [colourless]
Lime Water Emo Story RATE IT!!! Video I put together from a bunch of pictures i found around, based on a true story of when I went to a restaurant and ran out of water, i was eating that meal btw. SUBSCRIBE!!!

Use Limewater to Detect CO2
Sodium Carbonate and Hydrochloric acid The reaction between sodium carbonate and hydrochloric acid is investigated. Limewater is used to test the gas given off. (Music by free- Creative commons)
Match, lime, water, and cup trick This is something interesting that I learned while in Rhode Island, lmao.
Copper Carbonate and Sulfuric Acid The reaction between copper carbonate and sulfuric acid is investigated to determine the word equation. testing the gas using limewater. (Music from free- Creative commons)

TEST FOR CO2 GAS simple test for carbon dioxide gas conducted by year 10 students teacher: ms Jothy
Lime Water Breath Experiment Using lime water is a fun and easy way to test for the presence of carbon dioxide. The exhaled carbon dioxide is used to produce a precipitate of calcium carbonate with the lime water and using an indicater color will appear/disappear. This video shows such an experiment and how to perform one. Please feel free to leave any comments!

Decomposition of Malachite 2: Burning Experiment of Dr. El-Marsafy: A piece of malachite is heated in a glass pipette. A tissue paper wetted with methylated spirit is fixed in the pipette head. A tube connects the other end of the pipette with lime water in a vial. Observations: Colour changes from green to black., Water drops at the cool parts of the pipette. Gas bubbles make lime water milky. Ethanol vapour changes the black colour to the colour of copper. For explanation: /salzE11.html and /salz11.html (german)
Orange Lime water Here we go again, more flavored water...Will this bee good? or will it taste worse that the Lipstick water?
Let's Play Ys: The Ark of Napishtim 15 - To Limewater Cave Where much off-screen grinding shall be done... Maybe a little bit onscreen just to show some items you can find in the cave.

Lime milk and lime water Kalkmilch und Kalkwasser Lime milk -obtained by mixing a small amount of quicklime (= burnt lime) with water- is kept in a closed ampoule. After a few hours the solid forms a sediment on the bottom. The transparent liquid above it is lime water. A drop of it can be used to test for CO2 in the air ( By adding an indicator it can be demonstrated that it is an alkali: Kalkmilch -hergestellt durch Mischen einer Spatelspitze voll Branntkalk mit Wasser- trennt sich nach einigen Stunden in einen Niederschlag und einen klaren farblosen Überstand. Dies ist Kalkwasser. Es dient zum Nachweis von CO2 in der Luft ( Zusatz eines Indikators zeigt, dass es eine Lauge ist:

Chemical test for 3 invisible gases This is a resource for teachers to remind students of how to identify the three common, invisible gases used in high school laboratories. We have the Hydrogen pop test, The carbon dioxide limewater test and the oxygen test (re-lighting the splint). This video can be used as part of a class activity in which the reaction of sulfuric acid with calcium carbonate. This produces three products. One is an invisible gas which can be found with the tests shown. The other is a solid, which can be identified by evaporating all the water in the flask and the third product is a liquid which can be found by balancing the chemical equation.

magic with cups and lemon juice hi friends tis is a magic where u can u increase 1 cup of lime water to a big jar of lime water.enjoy watchin it
~ Ys VI: The Ark of Napishtim - Part 6 ~ Limewater Cave [1/4] I hate this damn place, also this place loves to LAG with fraps..so expect some lag. Also I got a lot of the items off recording cuz of the horrendous lag for some reason. Also how do you kill the Dark Adols?
