Question
**Assertion (A):** $H_3PO_3$ is a dibasic acid. <br>**Reason (R):** It contains two ionizable P-OH bonds and one non-ionizable P-H bond.
Answer: A
💡 Solution & Explanation
The structure of phosphorous acid shows only two hydrogens are attached to oxygen, making them acidic. The hydrogen attached directly to phosphorus does not dissociate. Basicity is therefore 2. [1, 4]
