Things your gonna need
Chemicals:
potassium ferricyanide
Potassium hydroxide
Ethanol
Concetrated sulfuric acid 96% will do
Equipment:
An erlenmeyer flask and a rubber stopper that fits with one hole in it
A glass tube that fits the hole
A beaker glass Will do but a second erlenmeyer with a rubber stopper with two holes Will be better
A hot plate
And a blow torch for bending the glass tube
you need to heat the tube with the blowtorch a few centimeters from the end so you can carfully bend it to 90 degrees do the same to the other end but make sure one side is longer so it wil fit to the bottom of the beaker glass or second erlenmeyer once this is done you can fill the first erlenmeyer with the potassium ferro cyanide 33,0 gram and the sulphuric acid 9,8 gram Once this is done you put the stopper in place and you can put the short end in the hole of the stopper
Now to make the potassium hydroxide solution 5,6 grams woud be exact but you want a slight excess for safety so 6,5 grams of potassium hydroxide Will be placed in the beaker (or second erlenmeyer) and add 100 ml of ethanol put the Beaker on the hot plate and stir with a glassrod to help the potassium hydroxide dissolve once dissolved you can put the long end of the tube inside the Beaker and the erlenmeyer on the hot plate now this is where things can get risky at this point the sulphuric acid react with potassium ferro cyanide to form cyanide gas that Will bubble inside KOH solution to create potassium cyanide any unreacted gas may escape and Harm you so be sure to do the reaction outside or under a fumehood if a second erlenmeyer is used with a two hole stopper you can use an additional glass tube connected to Some aquarium tubing to vent the leftover gas outside in any case when the reaction is done and the solvent cools down a white KCN should crystalize out of the solvent i do not want encourge anyone to do this since its not risk free at all butt it is possible to create KCN with very little money and easy to obtain chemicals as for the glassware you should look on Amazon
