Question

Though NaHSO4 solution releases H+ ions , why is it not called an acid

Answer 1

Answer:

NaHSO4 solution releases H+ ions, that why is it not called an acid. NaHSO4 is a very weak acid, in water it will dissociate into Na+ and HSO4- ions and HSO4- can give off some protons since it acts as a weak acid.

Answer 2

Though NaHSO4 solution releases H+ ions it is not an acid because:

• It is formed due to partial neutralization of NaOH and Conc.H2SO4.

• Sodium hydrogen sulphate is not an acid but it dissolves in water to give hydrogen ions, according to the equation NaHSO4​⇋H++Na++SO2-4
• Sodium hydrogen sulfate [NaHSO4 ] is an acid salt and is formed by the partial replacement of the replaceable hydrogen ion in a dibasic acid H2​SO4 .
• The [H] atom in NaHSO4 makes it behave like an acid.
• These acidic salts are formed when the amount of base taken is insufficient for the complete neutralization of the acid.
