During the electrolysis of aqueous solution of `HCOOK,` the number of gases obtained at cathode, anode, and total number of gases are

A

`1,2,3`

B

`1,2,2`

C

`2,1,3`

D

`2,1,2`

Text Solution

Verified by Experts

The correct Answer is:
b
At Cathode`:`
`H_(2)O+e^(-) rarr overset(c-)(O)H+(1)/(2)H_(2)(one)`
At anode `:`
`2HCOO^(c-) rarrr 2CO_(2)+H_(2)(` two`)`
`H_(2)` and `CO_(2)` at anode and `H_(2)` at cathode. So, number of gases as in `(b)`.
