Four metals P, Q, R and S are all obtained by the reduction of their oxides with carbon. Metal P is used to form a thin layer over the sheets of metal S to prevent its corrosion. Metal Q is used for electroplating tiffin boxes made of metal S whereas metal R is used in making car batteries. Metals Q and R form an alloy called solder. What are metals P, Q, R and S ? How have you arrived at this conclusion ? |

Answer» Metal P is zinc; Metal Q is tin; Metal R is lead; Metal S is iron. Metal P (zinc) is used to form a thin layer on metal S (iron) by the process of galvanisation to prevent its corrosion. Metal Q (tin) i s used for electroplating tiffin boxes made of metal S (iron). Metal R (lead) is used in making car batteries. Metals Q (tin) and R (lead) form an alloy called solder . |
