I had an aqueous solution of the sodium salt shown in my first post. C14H10Cl2NOO-Na+
I applied 18 volts to the solution with a copper cathode and graphite anode. H2 gas was produced at the cathode and an unknown white substance was produced at the anode. The white substance was less dense than the solution, so that's why I assumed some sort of hydrolysis had taken place, because the original salt settled at the bottom.
I'm assuming NaOH is also produced at the anode, but I am not sure what is being oxidized.
I'm an inexperienced undergraduate chemistry student, so I apologize if I'm asking the wrong questions or not giving enough info.
