The tarnished silver haveAg2S and the tarnish can be removed by placing the silverware in an aluminum pan containing an inert electrolyte solution, such as NaCl. Discuss the electrochemical principle for this procedure. When the standard reduction potential for the half-cell reaction Ag2S(s) + 2e- --> 2Ag (s) +S2- (aq) is -0.71 V.
