Sulphuric acid forms two types of salts with NaOH.

उत्तर
Sulphuric acid generates two types of salts with NaOH due to its dibasic nature, producing two hydronium ions per molecule when ionised in water.
\[\ce{NaOH + H2SO4 → \underset{sodium hydrogen sulphate}{NaHSO4} + H2O}\]
\[\ce{2NaOH + H2SO4 -> \underset{Sodium sulphate}{Na2SO4} + 2H2O}\]
