# Electrolysis of Beer

Electrolysis of water, means that the water is separated into hydrogen and oxygen. As beer also includes water, I initially thought electrolysis of beer would cause the water to separate, and the hydrogen and oxygen given off gas, leaving behind a higher concentrate alcohol.

However then realise that ethanol is also in beer (and is what makes you drunk it seems), and like water has an OH bond, so would the electrolysis also cause that to break?

(also does the rest of the molecule affect the strength of the OH bond, either stronger or weaker?)

• Sounds like a horrible thing to do to good beer! – Jon Custer Sep 16 '14 at 21:55
• The beer will conduct electricity mainly because of ions like Na, H, Cl and HCO3. Any such experiment end up with hell of non-separable dirt on anode: the mixture of chlorine, percarbonates and products of their reactions with organic and anode itself. – sa7 Nov 8 '16 at 14:42
• At best it will smell like bleach :) – sa7 Nov 8 '16 at 14:46

• My thoughts exactly! Incidentally, the electrochemical oxidation of ethanol over platinum can produce a whole pile of products, including acetaldehyde and acetic acid. If you're really lucky, you'll eventually get $CO_2$, so that C-O bond sticks around. – Geoff Hutchison Sep 17 '14 at 1:00
