From the following reaction which substance act as reducing agent ?
`HCHO+AgOtoHCOOH+2Ag`

A

HCHO

B

Ag

C

HCOOH

D

`Ag_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
A
`underset(+0)underset(darr)(HCHO)+underset(+1)underset(darr)(AgO)tounderset(+2)underset(darr)(HCOOH)+underset(0)underset(darr)(2Ag)`
Here, `Ag_(2)O` reduce into Ag while in HCHO it will be oxidised. So HCHO is reducing agent.
