Silver dissolves much more slowly in ferric perchlorate and nitrate than in ferric sulfate solutions. Here a detailed study of the rate in perchlorate solutions has been made, with the effect of concentration of ferric, ferrous, and silver ions, of other salts including sulfates, and of stirring speed, temperature, and electrical polarization. Two factors are responsible for the difference in rates: (a) silver perchlorate is more strongly adsorbed on silver than silver sulfate is, and (b) a sulfato–ferric complex ion reacts more rapidly than the normal hydrated ferric ion. Spectrophotometric evidence is given for the existence of the sulfato–ferric ion.
