Abstract : The composition of the argentate(I) complex formed in alkaline solutions of silver oxide has been studied by emf titrations with constant ionic medium (0.95 and 12.6 M NaOH, 1.15 and 11.5 M KOH) using Ag-AgI electrodes. The data indicate that only mononuclear complexes are formed; from this result, together with the solubility data of other workers, it is concluded that the formula of the complex is Ag(OH)2(-). No evidence has been found for the presence of the polynuclear argentate complexes proposed by some previous workers. The solubility product of Ag2O(s) in 3 M Na(ClO4) at 25C was determined as log K(sO) = log (Ag(+) conc.)(OH(-) conc.) = -7.42 AG(OH)2(-). (Author)
