Calcium perchlorate

Calcium perchlorate is a chemical compound, a perchlorate salt with the molecular formula Ca(ClO₄)₂.

Properties

Calcium chlorate is a strong oxidizer. It will react with sulfuric acid to release perchloric acid, while calcium sulfate is precipitated.

Calcium perchlorate is a white hygroscopic salt, soluble in water, ethanol and methanol.

Calcium perchlorate is difficult to purchase from suppliers, being a perchlorate.

Calcium perchlorate can be prepared by mixing a supersaturated solution of sodium perchlorate and calcium chloride.

2NaClO₄ + CaCl₂ → Ca(ClO₄)₂ + 2 NaCl

Calcium perchlorate is less soluble than sodium chloride and will crystallize from solution. Cooling the solution increases yield.

Calcium perchlorate is a strong oxidizer, but its hygroscopicity makes it less powerful. It is toxic if consumed.

In closed and sealed bottles, away from any organic material or strong mineral acid.
