How many coulombs are required for the oxidation of `1 mol` of `H_(2)O` to `O_(2)`?

A

`1.93xx10^(5)C`

B

`96500C`

C

`(92500)/(2)C`

D

`19.30xx10^(5)C`.

Text Solution

Verified by Experts

The correct Answer is:
a
Oxidation of `H_(2)O` to `O_(2)`
`2H_(2)Orarr4H^(+)+O_(2)+4e^(-)`
2 mol 4 mol
1 m ol 2 mol
`therefore` one mole of water release 2 moles of electrons on oxidation
1 mol of electron =96500C
2 moles of electrons =`2xx96500C`
