Explain the terms with examples.

Displacement reaction

Answer in Brief
Advertisements

Solution

Displacement reaction:
Displacement reaction is a chemical reaction in which a more reactive element displaces a less reactive element from its compound. Both metals and non-metals take part in displacement reactions. Chemical reactivity of metals is linked with their relative positions in the activity series.
A metal placed higher in the activity series can displace the metal that occupies a lower position from the aqueous solution of its salt.

For example:

Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)

2AI(s) + 3CuSO4(aq)  →  3Cu(s) + AI2(SO4)3(aq)

Fe(s) + CuSO4(aq) → Cu(s) + FeSO4(aq)

Pb(s) +CuCI2(aq) → PbCI2(aq) + Cu(s)
