Calcium permanganate is a chemical compound made up of calcium , oxygen and manganese . It is the calcium salt of the permanganic acid HMnO _{4, which is} unknown in the free state . Which is exclusively for the intense color of the salt permanganate - anion responsible.

Extraction and presentation

Calcium permanganate can be obtained by electrolysis of solutions of alkali manganates and chlorinated lime or, as with magnesium permanganate, from calcium chloride and silver permanganate .

${\displaystyle \mathrm {CaCl_{2}+2\ AgMnO_{4}\longrightarrow \ Ca(MnO_{4})_{2}+2\ AgCl\downarrow } }$

Chemical properties

Calcium permanganate Ca (MnO ₄ ) ₂ , like potassium permanganate, is a strong oxidizing agent .

use

Calcium permanganate is used:

• in textile production
• for bleaching paper
• for sterilizing water and during dental treatments
• as a catalyst in rocket fuels
• in coatings / fluxes of welding electrodes
• generally as an antiseptic, disinfectant and deodorant compound
