The hydrolysis effects on reduction of Be(II) ion in acetonitrile solutions was studied using differential pulse polarography and potential controlled coulometric techniques. The reduction process was found to be reversible with a coupled reaction before the charge transfer. For low contents (up to 0.5 mmol L –1 ), the [Be 3 (OH) 3 H 2 O 6 ] 3+ species are responsible for the coupled reaction to the electron transfer of hydrogen ion. For high Be(II) contents there are two electrode processes, one due to the electron reversible transfer of the [Be(H 2 O 4 )] 2+ species and another attributed to an irreversible transfer of hydrogen ion.
