if a small zinc rod is put into a solution of tin ii chloride sncl 2 tin

jun 13 so zinc acts as a reducing agent because it reduces tin ii cations to tin metal in other words the tin ii cations act as an oxidizing agent because they oxidize zinc metal to zinc cations now i think that the second part of the question features a lead rod being placed in a tin ii chloride aqueous solution
