Potassium nitrate is a chemical compound with the chemical formula KNO3. 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, which derives its

name from it. 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) and has been used since the Middle Ages as a food preservative.

►Production 

Potassium nitrate can be made by combining ammonium nitrate and potassium

hydroxide.

NH4NO3 (aq) + KOH (aq) → NH3 (g) + KNO3 (aq) + H2O (l)

An alternative way of producing potassium nitrate without a by-product of ammonia

is to combine ammonium nitrate and potassium chloride, easily obtained as a

sodium-free salt substitute.

NH4NO3 (aq) + KCl (aq) → NH4Cl (aq) + KNO3 (aq)

Potassium nitrate can also be produced by neutralizing nitric acid with potassium

hydroxide. This reaction is highly exothermic.

KOH (aq) + HNO3 → KNO3 (aq) + H2O (l)

On industrial scale it is prepared by the double displacement reaction between

sodium nitrate and potassium chloride.

NaNO3 (aq) + KCl (aq) → NaCl (aq) + KNO3 (aq)

 
►Specification

►Application
 
     

Historically, nitric acid was produced by combining sulfuric acid with nitrates such

as saltpeter. In modern times this is reversed: nitrates are produced from nitric acid

produced via the Ostwald process.
