The reaction of white phosphorus on boiling with alkali in inert atmosphere resulted in the formation of product A . The reaction 1 mol of A with excess of AgNO 3 in aqueous medium gives ________ mole(s) of Ag . (Round off to the Nearest Integer).

Correct answer

0

Step-by-step solution

P 4 + 3 OH - + 3 H 2 O → PH 3 + 3 H 2 PO 2 - A H 2 PO 2 - 1  mole  + 4 Ag +  excess  + 2 H 2 O → H 3 PO 4 +   4 Ag   + 3 H + 4  mole
