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