The standard `EMF` of decinormal calomel electrode is `0.268 V`. The `EMF` is

A

`-0.298V`

B

`0.327V`

C

`-0.327V`

D

`0.298V`

Text Solution

Verified by Experts

The correct Answer is:
b
`E=E^(c-)-(0.059)/(2)log [Cl^(c-)]^(2)`
`=0.268-(0.059)/(2) log (0.1)^(2)`
`=0.268-(0.059)/(2) xx log 10^(-2)`
`=0.268+0.059=0.327V`
