Caro's acid (or peroxymonosulfuric acid) is an equilibrium product obtained by mixing H2O2 with sulfuric acid.
H2O2 + H2SO4 <--- ---> H2SO5 + H2O
It is used in the mining and hydrometallurgy industries for digesting ores and separating components, and for destroying cyanide residuals. Caro's acid is not sold as a product but is produced onsite at the point of application. FMC has developed several models of generators used for on-site production of Caro's acid.
