Four alkali metals ` P,Q ,R` and `S` are having respectively standard electrode potentials as ` -3.05V ,- 1. 66V , -0 . 40 V` and ` 0. 80 V`. Which one will be th most reducing agent ?

A

`P`

B

`Q`

C

`R`

D

`S`

Text Solution

Verified by Experts

The correct Answer is:
A
The more ngative the electrode ptential, the lesser the tendncy of the metal to undergo reduction and therefore metal would act as stronge reducing agent.
