if I have concentrated acetic acid (99%) what are the out put gases during electrolysis? If I use concentrated acetic acid (glacial acetic acid($\ce{CH3COOH}$)) as an electrolyte. What ions are produced at the anode and cathode?
Can I get ethanol with it ($\ce{C2H6O}$)? If not, what would be the products?
Upon electrolysis, organic acids will lose the carboxyl group and dimerize.
This is known as the Kolbe electrolysis:

In the case of electrolysis of acetic acid, ethane and $\ce{CO2}$ will be formed.
