Strontium nitrate Totally Explained

Everything about Strontium Nitrate totally explained

| Section2 = | Section3 = }}
Strontium nitrate (Sr(N O₃)₂) is an acid salt of strontium. It is used as an oxidizer and colorant in fireworks.

Preparation

Strontium nitrate is typically generated by the reaction of nitric acid on strontium carbonate. ť 2 HNO₃ + SrCO₃ → Sr(NO₃)₂ + H₂O + CO₂

Uses

Like many other strontium salts, strontium nitrate is used to produce a rich red flame in fireworks and road flares. The primary difference strontium nitrate has over the other salts is the fact it's an oxidizer. This provides two uses in pyrotechnics.
Solutions of Sr(NO₃)₂ reacts with sulfuric acid to precipitate SrSO₄, a precursor to the phosphor strontium sulfide.

Health warning

If strontium nitrate is heated to the point of decomposition it'll produce strontium oxide and release toxic nitrogen dioxide gas.
