strong oxidizing ability allowed for stabilization of the unusual oxidation state of 2+ for silver which was observed by preparing an analogous silver (II) complex by reacting silver (I) nitrate with ammonium peroxodisulfate in the presence of pyridine. IR spectra for the three products were obtained‚ as well as qualitative tests for Product A (K2S2O8) in comparison with H2O2‚ confirm the presence of the peroxodisulfate anion and the identity of the individual yields.
