Question

Sulphuric acid is said to be a dibasic acid. What is meant by the term 'dibasic'?

Answer 1

Dibasic Acid

1. The term ‘dibasic’ refers to two ionizable hydrogen atoms present in a single acid molecule.
2. Sulphuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$ is an example of a dibasic acid because it dissociates fully to produce two hydrogen ions successively.
3. Hence, sulphuric acid is said to be a dibasic acid due to the presence of two replaceable hydrogen atoms.
