In the electrolysis of alkaline water, a total of 1 mole of gases in evolved. The amount of water decomposed in

A

1 mole

B

2 moles

C

`(1)/(3)` mole

D

`(2)/(3)` mole.

Text Solution

Verified by Experts

The correct Answer is:
D
`H_(2)OrarrH_(2)+1//2O_(2)`
1 mole of water gives on electrolysis `(3)/(2)` moles of gases
`therefore ` To produce 1 mole of gases water electrolysed `=(2)/(3)` mol
