During the electrolysis of aqueous solution of `HCOOK,` the number of gases obtained at cathode, anode, and total number of gases areA. `1,2,3`B. `1,2,2`C. `2,1,3`D. `2,1,2` |

Answer» Correct Answer - 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)`. |
