The hydrolysis equilibria of the copper(II) ion in heavy water have been studied at 25°C by measuring the deuterium-ion concentration by means of a commercial glass electrode. The total copper(II) concentration was varied between 50 and 90 mM, while the concentration of the perchlorate ion was held constant at 3M by the addition of NaClO<SUB>4</SUB>. A hydrolyzed copper(II) perchlorate solution was gradually acidified up to the point where hydrolysis was negligible by the use of constant-current coulometry. The experimental data, which indicate a slight hydrolysis in the log <I>d</I> range from –4.0 to –5.26, can be explained by assuming these equilibria;<BR>& Cu^2++D_2O=CuOD^++D^+,logβ_1,1=-7.71±0.07;<BR>& 2Cu^2++2D_2O=Cu_2(OD)_2^2++2D^+,logβ_2,2=-11.46±0.04.
