Abstract

Stepwise complex formation between gallium(III), indium(III) and nitrite ions has been studied potentiometrically by means of a glass electrode in an aqueous sodium perchlorate medium of unit ionic strength at 25.0°C. In both systems only mononuclear complexes of moderate stability were formed over the range of concentrations used. No evidence has been found for the formation of polynuclear and/or acid complexes. Values of the overall constants for the formation of Ga(NO2)2+, In(NO2)2+, [Formula ommited] and In(NO2)3are 130 ± 40M-1, 390 ± 110M-1, (1.04 ± 0.29)104M-2, and (8 ± 5)104M-3, respectively.
