Sodium Nitrate Formula

Sodium Nitrate formula, which is also known as Nitrate of soda formula, or Cubic nitre formula is given in this article. It is an inorganic nitrate salt of sodium (Na) which consists of sodium as a cation i.e Na+ and nitrate as an anion i.e NO3-. The nitrogen atom from the nitrate ion bonds to three oxygen atoms through two single bonds and one single bond. The chemical or molecular formula for sodium nitrate is NaNO3.

It is a white crystalline solid, odourless and has a slightly bitter taste. It is non-combustible and is highly soluble in water, hydrazine and ammonia. It dissolves in alcohol, slightly dissolves in pyridine, and completely insoluble in acetone.

It is naturally bound to the mineral deposits known as caliche ore found in Peru and Chile. Nitrates are accumulated on the land through

  • Precipitation of marine-fog
  • Sea-spray oxidation or desiccation and
  • Gravitational settling of airborne KNO3, Na2SO4, I, NaNO3, and NaCl.

It is widely used in the manufacturing pyrotechnics, glass, food preservatives, propellant, fertilizers, smoke bombs, pottery enamels, and solid rocket.
