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
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.
Potassium nitrate can be made by combining ammonium nitrate and potassium
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)
Potassium nitrate is used in fertilizers as a source of nitrogen and potassium
– two of the macronutrients for plants. When used by itself, it has an NPK
rating of 13-0-44.
