Calcium perchlorate

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

Properties

Chemical

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

Physical

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

Availability

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

Preparation

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.

Projects

• Make concentrated perchloric acid

Handling

Safety

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

Storage

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

Disposal

Calcium perchlorate can be destroyed with metallic iron under UV light, in the absence of air.
