An iron nail placed in a solution copper (ll) tetraoxosulphate (VI) is soon covered with a deposit of copper which of the following equations represents the reactions ?
Fe 2+ (aq) + Cu(s) → Fe 3+ + Cu 2+ (aq)
Fe 2+ (aq) + Cu(s) → Fe(s) + Cu2+ (aq)
Fe (s) + Cu2+ (aq) → Fe2+(aq) + Cu2+ (aq)
Fe(s) + Cu2+ → Fe2+(aq) + Cu(s)
