What happens when (a) Dilute sulphuric acid is poured on a copper plate? (b) Iron nails are placed in copper sulphate solution? Write word equations of the reactions involved.


(a)Copper(metals) react with sulphuric acid and produce sulphuric dioxide and water. Copper + Sulphuric acid → Copper sulphate + sulphur dioxide (b) Iron is more reactive than copper and thus displaces copper from copper sulphate solution to form iron sulphate and copper metal. Iron + Copper sulphate → Iron sulphate + Copper.
