Abstract

[Introduction]

The equilibrium between palladous and palladic chlorides and chlorine in hydrochloric acid solution seems not to have been previously measured, and no physico-chemical studies have been made as to the state in which bivalent and quadrivalent palladium exist in chloride solutions. It is well known, however, that from such solutions salts of the types R₂Pd-Cl₄ and R₂PdCl₆ separate, and it is probable that in such solutions the palladium exists mainly or wholly in the form of the corresponding ions PdCl₄^-- and PdCl₆^--. In that case the equilibrium to be here considered would be expressed by the simple equation: PdCl₄^-- + Cl₂ = PdCl₆^--.
