Electrolusis involves electronation and de-electronation at the redpective electrodes. Anode of electrolytic cell is the electrode at which de-electronation takes place whereas at cathode electronation is noticed. If two or more ions of same charge are to be electronated or de-electronated, the ion having lesser discharge potential is dischargeed. Discharge potential of an ion refers for `E_(OP)^(@)` or `E_(RP)^(@)` as the case may be. The products formed at either electrode is given in terms of Faraday's laws of electrolysis i.e., `w = (Eit)/(96500)`
A. During electrolysis of `CH_(3)COONa_((aq.))` the mole ratio of gases formed at cathode and anode is :

Options

A. `1 : 2`
B. `2 : 1`
C. `3 : 1`
D. `1 : 3`

Answer

D

Explanation

Anode : `2CH_(3)COOH^(-) rarr ubrace(C_(2)H_(6)+2CO_(2))_("3 mole") + 2e`,
Cathode : `2H^(+) + 2e rarr underset(1 "mole")(H_(2))`
