potassium nitrates

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 m..

By Treating Metals with Nitric Acid The reaction of nitric acid with sodium, potassium and calcium is too explosive. Hence, these metals cannot be used to prepare their nitrates. ..

Preparation of Oxygen - From Nitrates - Metallic nitrates, when heated, give out oxygen. At the same time, most of them also give out a reddish brown gas - nitrogen dioxide, NO 2 . Thus, these nitrates cannot be used to prepare oxygen. However, sodium and potassiu..

Action of heat : When nitric acid or nitrates of metals other than sodium and potassium are heated, reddish brown fumes of nitrogen dioxide are produce..

Calculate the percentage loss of mass suffered by potassium nitrate, when it is completely decomposed by heat. (Relative atomic mass of K=39, N=4, O=1..

This method is used to separate two or more solutes, by making use of their difference in solubility. If we want to separate potassium nitrate from a mixture that contains about 80 g of potassium nitrate and 20 g of sodium chloride. We will dissolve this mixt..

It is the weakening of seed coats by mechanical abrasions or chemical treatments. Mechanically, the abrasions are caused by machine threshing, vigorous shaking. Chemically, the seeds are treated with chemicals like potassium nitrate, thiourea, ethylene, chlorohydrine to make the..
