Sodium diperoxochlorate

Properties, data and information sources.

 

Contents

Sodium diperoxochlorate is the sodium-containing neutralization form of peroxochlorine-containing oxospecies, which originate from so-called diperoxochloric acid. It is not an isolated salt with a defined stoichiometry, but rather an ionic equilibrium system in aqueous solution, the composition of which depends on the pH value and the ionic strength.
