Text Solution

Verified by Experts

The correct Answer is:
D
The acids which are obtained from the minerals present in earth are called mineral acids. Weak acid is the acid in which less than 30% molecules ionize in water. Dibasic acid is the one which furnishes two `H^(+)` ions by one molecule of an acid. And hence `H_(2)SO_(3)` is a dibasic weak mineral acid.
