Silver is less reactive compared to iron. At low temperatures it does not react with acid rain. However, at higher temperatures, it forms a layer of insoluble Silver sulfate upon reaction with acid rain. Hence coating of silver will protect iron from damage. Equation is given below: $2Ag(s) + 2H_{2}SO_{4} (aq) → AgSO_{4}(s) + SO_{2}(g) + 2H_{2}O (l)$
