A study of Pd2+(aq) hydrolysis. Hydrolysis constants and the standard potential for the Pd,Pd2+ couple

Abstract
Equilibrium constants have been determined both by pH titration and spectrophotometric methods for the stepwise formation at 25° of Pd(OH)2(aq) from Pd2+(aq) and OH(aq). A standard electrode potential has been measured for the reaction Pd = Pd2++ 2e. Possible formation of polynuclear species is considered and discussed.
