# Why can't I see any bubble in my anode during my electrolysis experiment

I am doing an electrolysis experiment using this apparatus The left side is the anode and the right side is the cathode. I am using two 9v battery in series (total 18V DC) to power my apparatus. During the experiment, I see moderate amount of bubbles on my cathode, but no bubbles on my anode, why is that? The cathode is a system of paralle wire because I want to see enough OH- pushing the neutral water molecules toward the cathode.

Per water molecule $$\mathrm{H_2O}$$ there is double the amount of hydrogen than oxygen. The hydrogen ions will get discharged at the cathode whereas oxygen will be formed at the anode. The discharge should happen also at the anode (otherwise there won't be any current) but you will see less bubbles due to the above.
