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
