How to make aluminum nitrate nonhydrate, one of the chemicals needed to make glow in the dark powder. In an upcoming video we'll need aluminum nitrate nonahydrate. The chemical formula is Al(NO3)3.9H2O Warning: These reactions must be performed outside or in a fumehood. At first it might seem that simply mixing aluminum with nitric acid can be done. But interestingly enough, aluminum is immune to the effects of nitric acid. So in order to make aluminum nitrate a two step method is needed. First the aluminum is dissolved in concentrated hydrochloric acid. This produces a solution of aluminum trichloride. ... https://www.youtube.com/watch?v=u4Ha1SJrazY

We make silver acetate used for making conductive silver ink. Silver acetate is made by reacting 20g of silver nitrate in 10mL of water with 20g of sodium acetate in 50mL of water and filtering the precipitated silver acetate. It is washed several times with water and allowed to dry. ... https://www.youtube.com/watch?v=2J6V4acKels

In this video we recover platinum from platinum containing laboratory chemical waste. This method was heavily drawn from the method at this citation: G.B. Kauffman, L.A. Teter, Inorg. Synth. 7 (1963) 232–236 Now laboratory chemical waste needs to be incinerated first to remove all organic compounds. Chemical methods are not used because they are more expensive and cannot deal with all types of organic residues. Incineration is the cheapest broadly applicable solution. We've already done this in part 1 of this series: https://www.youtube.com/watch?v=xeKZdJ1As7I Now in this video we process the platinum concentrate powder into platinum metal. We're using 2.4g of platinum concentrate but your numbers may be adjusted accordingly First we boil the powder with some concentrated hydrochloric acid. About 10-25ml of acid per gram of platinum concentrate. The mixture is then filtered and the residue is subjected to aqua regia digestion. About 4mL of aqua regia (3ml hcl and 1 mL nitric acid) for every gram of platinum concentrate. The mixture is gently heated to drive the reaction. After all the nitrogen oxides have been driven off the mixture is filtered and is again subjected to aqua regia treatment. This is repeated until the filtrate is a constant shade of light yellow or until stannous chloride testing shows no metals dissolving. The residue is then weighed to determine how much metal was dissolved. ... https://www.youtube.com/watch?v=7B-EwKOqqv4
