NCERT Science Class 10 Class 10 Science Exercise 1.1, Q5 short

Prove that the reaction below is a displacement reaction: Pb_(s) + CuSO4(aq) → PbSO4(aq) + Cu_(s)

Prove that the reaction below is a displacement reaction:

Pb(s)+CuSO4(aq)PbSO4(aq)+Cu(s)\mathrm{Pb}_{(s)} + \mathrm{CuSO}_{4(aq)} \longrightarrow \mathrm{PbSO}_{4(aq)} + \mathrm{Cu}_{(s)}

Verified Answer

This is a displacement reaction because lead (Pb\mathrm{Pb}) displaces copper (Cu\mathrm{Cu}) from copper sulphate solution. The more reactive metal (lead) displaces the less reactive metal (copper).

The reaction is:

Pb(s)+CuSO4(aq)PbSO4(aq)+Cu(s)\mathrm{Pb}_{(s)} + \mathrm{CuSO}_{4(aq)} \longrightarrow \mathrm{PbSO}_{4(aq)} + \mathrm{Cu}_{(s)}
