Chemical Properties of Strontium Chloride – SrCl2
- Strontium chloride reacts with hydrogen fluoride gas resulting in the formation of strontium fluoride and chlorine gas.
SrCl2(aq) + 2HF(gas) → SrF2(solid) + Cl2(gas)
- Strontium chloride reacts with sulfuric acid forming strontium hydrogen sulphate and hydrogen chloride.
SrCl2 + 2H2SO4 → Sr(HSO4)2 + 2HCl
