Which of the following phosphorus oxyacids can act as a reducing agent?
- A \(\mathrm{H}_{3} \mathrm{PO}_{3}\)
- B \(\mathrm{H}_{3} \mathrm{PO}_{4}\)
- C \(\mathrm{H}_{2} \mathrm{P}_{2} \mathrm{O}_{6}\)
- D \(\mathrm{H}_{4} \mathrm{P}_{2} \mathrm{O}_{7}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{H}_{3} \mathrm{PO}_{3}\)
Step-by-step Solution
Detailed explanation
Oxyacid of phosphorus which contains \(\mathrm{P}-\mathrm{H}\) bonds can act as a reducing agent. \(\mathrm{H}_{3} \mathrm{PO}_{3}\) contains one \(\mathrm{P}-\mathrm{H}\) bond and hence acts as a reducing agent.
