Nitrate Chemical

Potassium nitrate is a chemical compound with the chemical formula KNO 3. It is an ionic salt of potassium ions K+ and nitrate ions NO3, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter. It is a source of nitrogen, from which it derives its name. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter or saltpetre. Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder).[6] In processed meats, potassium nitrate reacts with hemoglobin and generates a pink color.

Sodium nitrate is the chemical compound with the formula NaNO . This alkali metal nitrate salt is also known as Chile saltpeter to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter. Sodium nitrate is a white solid very soluble in water

Copper(II) nitrate, Cu(NO3)2, is an inorganic compound that forms a blue crystalline solid. Anhydrous copper nitrate forms deep blue-green crystals and sublimes in a vacuum at 150-200 C.[3] Copper nitrate also occurs as five different hydrates, the most common ones being the trihydrate and hexahydrate. These materials are more commonly encountered in commerce than in the laboratory.

Manganese(II) nitrate are the inorganic compounds with formula Mn(NO). Each formula unit is composed of one Mn cation and two NO anions and varying amounts of water. Most common is the tetrahydrate Mn(NO)4HO, but mono- and hexahydrates are also known as well as the anhydrous compound
