Elementary Productions: Tollens' reagent, Silver Mirror Test The Silver mirror test is a qualitative test for aldehydes, in this case, Glucose. The Diamminesilver(I) Complex is made by adding Silver Nitrate to water, and to this add Sodium HYdroxide. This precipitates Silver Oxide. The Silver Oxide is reacted with Ammonia to give the Silver Complex....

Dragendorff Reagent A few things to say: I up loaded this video because I dont feel like I showed the reaction between bismuth and nitric acid well enough in my last video and because I got a lot of questions about dragendorff reagent after my last video. At the beginning you could see a lot of nitrogen dioxide. I know this gas is very harmful and it looks like the camera is right in it, but in actuality I was pretty far away from it. Please be safe when using nitric acid, nitrogen dioxide gas is very harmful. bismuth nitrate will not decompose to subnitrate in acidic conditions, hence the sodium carbonate. I did a quick caffination test without much success. It worked well with the pure caffeine I made in a previous video but I dont think caffeine precipitates as well as quinine. At 4:50: sorry I forgot to silence my phone :P. Currently im using my phone to shoot videos (I want to change that soon) and thats my ringtone! Anyway, a link to Chemical Myst's channel: Anyway thats it. I probably wont post for a while but as always feel free to comment or message, thanks!

Grignard Reagent Synthesis This is one step of my research work.... Reaction environment should be water free. For that you can supply nitrogen to the reaction system as shown in the video. Brown colour viscous solution like shown in the video should be the ultimate result. (Grignard reaction mixture is in the first two necks round bottom flask. Three necks round bottom flask contain another reaction mixture). First you should provide enough heat to initiate the reaction. After that remove the heat form the reaction mixture, because reaction is highly exothermic.
