Hello,
I know that you can electrolyse water to produce hydrogen and oxygen, i also know that you cannot electrolyse alcohols like methanol.

So what happens if you have a solution of alcohol and water?

Does the water still decompose and the the alcohol remain?

Thanks

Yep. Although the reality is slightly more complicated, as you may expect some other reactions - like alcohol oxidation/reduction - on electrodes.
