Other inorganic electrolytic processes

Abstract

In this chapter, the electrolytic preparation of inorganic compounds other than chlorine, alkalis and metals will be discussed. The processes are, in general, low-tonnage but have an established or developing position in industrial practice. The compounds prepared by electrolytic processes are: (1) the strong oxidizing agents (e.g. KMnO₄, NaC1O₃, K₂Cr₂O₇, Na₂S₂O₈, F₂, H₂O₂ and O₃; the electrolytic generation of hypochlorite is considered in Chapter 7); (2) metal oxides which are particularly active when prepared anodically (e.g. MnO₂ and Cu₂O); (3) a variety of metal-ion redox species in solution (e.g. Cr(II), Ce(Iv), Ti(III) (see also Chapter 6)); (4) hydrogen/oxygen by water electrolysis; and (5) metal salts via anodic dissolution of the metal.
