Q
Materials: Metals and Non-metals

Question:

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.

Answer:

(a) When sulphuric acid is poured on a copper plate, no reaction will take place as copper is a less reactive metal.

(b) Iron is a more reactive metal than copper. So, when the iron is placed in copper sulphate solution, iron displaces copper from its solution to form iron sulphate.
