Calcium perchlorate

Ca(ClO4)2 is a common chemical on the soil of planet Mars, counting for almost 1% of the Martian dust, by weight.

Calcium perchlorate is a strong inorganic oxidizing agent, enhancing the combustion of other substances that can potentially lead to explosion.

[3][4] Electrolyte conductance of Ca(ClO4)2 and double charged metal cations in the organic solvent acetonitrile has been tested.

[5] The interest in metal cation perchlorate interactions with photosensitive ligands has increased due to the development of highly specific fluorescence indicators.

[8] Calcium perchlorate is slightly toxic to humans, by ingestion or inhalation of dust particles, or (less so) by skin contact.

E.g. water Instability 1: Normally stable, but can become unstable at elevated temperatures and pressures. E.g. calcium Special hazard OX: Oxidizer. E.g. potassium perchlorate
