Question

explain why an aqueous solution of sodium sulphate is netural while sodium carbonate is basic in nature

Answer 1

Sodium sulphate is made from a strong acid and a strong base i.e, H2SO4 + NaOH = Na2SO4 + H2O... Therefore, the strong base completely neutralizes the acid and forms a neutral salt.

And in case of sodium carbonate, it is made from a weak acid and a strong base i.e, NaOH + H2CO3 = Na2CO3 + H2O.... Therefore, the weak acid remains dominated by the strong base and the salt formed is basic in nature.
