Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Calcium perchlorate is a chemical compound, a perchlorate salt with the molecular formula Ca(ClO4)2. It is commonly encountered as tetrahydrate.
Calcium chlorate is a strong oxidizer. It will react with sulfuric acid to release perchloric acid, while calcium sulfate is precipitated.
Calcium perchlorate is difficult to purchase from suppliers, being a perchlorate.
- 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.
- Make concentrated perchloric acid
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.
