Explain why heat of neutralisation of strong acid and weak base is less than `57.1 kJ`.

Text Solution

Verified by Experts

It is because weak bases do not ionise completely in aqueous solution. Therefore, some enegry is required for their complete ionisation and that is why net energy released is less.
