Potassium is very toxic and corrosive and flamable in air. You can not buy it as a powder in a bag like salt or sugar. And it is the unsafest way to produce hydrogen. So don't try!!
It is mined but there are different types Monoammonium phosphate Sodium bicarbonate Potassium bicarbonate Potassium bicarbonate & Urea Complex Potassium Chloride these are just the powder type
Baking powder is a mixture of tartaric acid and bicarbonate of soda (sodium hydrogen carbonate). The acid releases gas (carbon dioxide) from the bicarbonate. Depending on the formulation, the tartaric acid may be replaced by cream of tartar (potassium bitartrate, also called potassium hydrogen tartrate).
Magnesium powder and 4 mol1-1 acid
Potassium nitrate is used to make fireworks and black powder (which is used in gun powder).
to stop it spreading
Yes - and it's corrosive too !
Sodium hydrogen carbonate is baking powder.
Potassium bitartrate, also known as potassium bitartrate or potassium hydrogen tartrate, has formula KC4H5O6. It is a byproduct of wine-making. It is also known as cream of tartar. It is the potassium acid salt of tartaric acid. It is a powder used in candy making, in frosting, to stabilize egg whites and in baking. It's made from tartaric acid and is found in some versions of baking powder.
Potassium nitrate is the oxidizer used in black powder. Although other oxidizers are stronger(potassium perchlorate for example), it must not be replaced by them. If the term used is black powder, potassium nitrate is the only oxidizer that ought to be used.
how to make potassium methyl siliconate powder
copper+nitric acid > copper nitrate+hydrogen copper+sulpuric acid> copper sulphate+ hydrogen copper+potassium chloride> copper chloride+ hydrogen copper+ zinc carbonate (powder metal) > copper+ zinc + water + carbon dioxide zinc+nitric acid > zinc nitrate+ hydrogen etc just replace the copper in the above equations with 'zinc' for all the zinc solutions x
