The common name of potassium nitrate is Bengal salt petre or nitre. It can be prepared by treating the oxide, hydroxide, carbonate or hydrogen carbonate salts of potassium with nitric acid. It is a colorless crystalline solid, soluble in water. When heated, it first melts and t..

A mixture of potassium chlorate (KClO 3 ) and manganese dioxide (MnO 2 ) (4 : 1) is heated in a dry test tube. The oxygen evolved is collected over water. The decomposition of KClO 3 is accelerated even at lower temperatures as MnO 2 acts as a catalyst...

Preparation of Potassium Bicarbonate - Pass carbon dioxide through a solution of potassium carbonate for some time. Evaporate the resulting solution to dryness when potassium bicarbonate crystals separate ou..

During fermentation of grape juice, a brown crust is formed at the top and is called argol, which contains potassium hydrogen tartrate. It is used for the prepartation of tartaric acid and Rochelle salt (potassium sodium tartrate..
