The composition of the argentateI 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 AgOH2-. No evidence has been found for the presence of the polynuclear argentate complexes proposed by some previous workers. The solubility product of Ag2Os in 3 M NaClO4 at 25C was determined as log KsO log Ag conc.OH- conc. -7.42 AGOH2-. Author
