I recently conducted a simple experiment for school involving the electrolysis of water.
I changed the concentrations of an ionic compound to determine its effect on the rate at which the products of the lysis of water are formed. I used graphite rods for the electrodes. These shed quite heavily.
I noted this down in my qualitative data, but I was wondering whether this excess graphite may have bonded with some of the hydrogen produced at the cathode to form hydrocarbons?
