प्रश्न
Give reason for the following:
Sodium hydrogen sulphate is not an acid but it dissolves in water to give hydrogen ions, according to the equation
\[\ce{NaHSO4 <=> H+ + Na+ + SO^2-_4}\]
उत्तर
Sodium hydrogen sulphate [NaHSO4] is an acid salt and is formed by the partial replacement of the replaceable hydrogen ion in a dibasic acid [H2SO4]. The [H] atom in NaHSO4 makes it behave like an acid.
So, on dissolving in water, it gives hydrogen ions.
