Which of the Phosphorus oxoacid can create silver mirror from AgNO 3 solution?

Options

  1. AHPO 3 n
  2. BH 4 P 2 O 5
  3. CH 4 P 2 O 6
  4. DH 4 P 2 O 7

Correct answer

B. H 4 P 2 O 5

Step-by-step solution

The oxyacid HPO 3 n has different structures based on the value of n. If n=3, The oxyacid H 2 P 2 O 5 has the following structure. The structures of the H 4 P 2 O 6 and H 4 P 2 O 7 are Oxyacid having P - H bond can reduce AgNO 3 to Ag . Hence, H 4 P 2 O 5 can create silver mirror with silver nitrate.
