Summary
The hydrolysis of the palladium(II) ion in a sodium chloride medium was studied by the e.m.f. method at 25 °C. The data show that the extent of the palladium hydrolysis depends upon the concentration of both palladium and sodium chloride medium. Thus, at a definite pH, the extent of the hydrolysis increases with increasing concentration of palladium, but decreases with increasing concentration of sodium chloride. The stability constants of the complexes obtained, PdOH+ and Pd4(OH) 4+4 , also differ slightly depending upon the concentraton of sodium chloride. The observed medium effect is in agreement with the linear free energy relationship proposed for the metal ion hydrolysis.
