Question

Define basicity of an acid. One molecule of an acid on ionization produces two hydrogen ions in an aqueous solution. Name this acid.

Answer 1

Basicity:

• The number of hydrogen ions $\left({\mathrm{H}}^{+}\right)$ produced per molecule of acid in an aqueous solution is known as its basicity.

Dibasic acid:

• A substance that produces two hydrogen ions $\left({\mathrm{H}}^{+}\right)$ per molecule of the acid, when completely dissociated in water is referred to as a dibasic acid.
• Name of a dibasic acid is Sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$.
