@sotirispagalos Or a graphite ;)

Please make english subtitles! Those experiments look great, and it is a big waste many people cannot understand it!
-
Its because your anode must be a metal. Change your anode to platinum or stainless steel as said above and it should work
-
That is exactly what was wrong, thank you so much!! Im a new chemistry teacher and teaching about how the oxygen combines with the anode if its metal and wont appear as oxygen gas was a lesson in itself!!!

No, it is just the decomposition water into its components Hydrogen and Oxygen by means of electric energy. In this case we stop and do not gain back the chemical energy from Hydrogen.

When I did this plenty of hydogen gas was being given off at the cathode but no oxygen was being formed at the anode. I was running 12V through the acidified water. Am I doing something wrong?

This happens when anode is made of metal thay can be easily oxidised.
So the produced oxygen is chemicaly combined with the metal of anode fixing the oxide of the metal (solid), and does not appear as free,gas, element oxygen.
You need to replace the metal of anode with some stainless metal ( better a wire of platinum, wich is a litle expensive)
