Question

Write chemical equation when hypophosphorous acid is added to agno3 solution

Answer 1

2Ag + H3PO3 + 2HNO. Silver(I) nitrate react with hypophosphorous acid and water to produce silver, phosphorous acid and nitric acid. Hypophosphorous acid - concentrated solution. This reaction takes place at a temperature near 50°C

Answer 2

Answer:

The answer is $2AgNO_3 +H_3PO_3 +H_2O$  →  $2Ag +H_3PO_4 + 2HNO_3$

Explanation:

When hypophosphorous acid ($H_3PO_3$) is added to the silver nitrate solution, it reduces the Siver nitrate in the solution ($AgNO_3$) into Silver. Since the hypophosphorous acid is a powerful reducing agent it reduces the silver nitrate to silver and forms phosphoric acid ($H_3PO_4$).

The reaction is as follows:

 $2AgNO_3$      +      $H_3PO_3$       $+ H_2O$        → $2Ag + H_3PO_4 +2HNO_3$

Silver Nitrate   Hypophosphorous           Silver    Phosphoric acid
