How can I make home made potassium chloride?

Question

If not KCl, Potassium Nitrate: KNO3
A Chemistry investigatory report

Answer 1

Potassium chloride is indeed inexpensive and readily available at most pharmacies. However, It could be made at home long before there were pharmacies.

If someone tells you to react Potassium metal with Hydrochloric acid, they are correct that this will make Potassium chloride, but this is expensive and dangerous even when done by experienced chemists in well provisioned laboratories.

Burning dry wood (you could use wood shavings) will leave you with a white powder called Potash. This is how the element Potassium got it's name. Potash is mostly Potassium carbonate with a small amount of Potassium oxide or hydroxide and some Sodium salts.

If this ash is dissolved in water, filtered and then neutralized with Hydrochloric acid (which can be purchased in hardware and building supply stores as Muriatic acid), you will end up with crude Potassium chloride.

The crude salt can be dissolved in boiling water and recrystallized to get a more pure product. This is like making rock salt, but you are using Potassium instead of Sodium.

If Nitric acid is used instead of Hydrochloric acid, you get crude Potassium nitrate.

How To Make Potassium Chloride

Answer 3

Get some potassium metal and melt it. You don't need too much heat as it melts at 62C. Don't use an aluminum pan because mom won't be happy. Then bubble chlorine gas through it. That will definitely make KCl.

Answer 5

Get HCl and pour it to pure potasium.

Of course, a gas will evolve and that is H2.

i think you are better off buying them as they are not that expensive. you could cause more damage to yourself bu experimenting.
