MCQ
For ${H_3}P{O_3}$ and ${H_3}P{O_4}$ the correct choice is
- ✓${H_3}P{O_3}$ is dibasic and reducing
- B${H_3}P{O_3}$ is dibasic and non-reducing
- C${H_3}P{O_4}$ is tribasic and reducing
- D${H_3}P{O_3}$ is tribasic and non-reducing
✓
Answer
Correct option: A.
${H_3}P{O_3}$ is dibasic and reducing
(a) $H - O - \mathop {\mathop P\limits_ \downarrow ^| }\limits_O^H - OH$, hence it is dibasic. It acts as reducing agent also.
