Why We See More Bubbles In Cathode Beaker Than Anode Beaker During The Electrolysis Of Acidified Water?

In electrolysis water (H₂O) splits into Hydrogen(H₂) and Oxygen (O₂)

The Oxygen is released at the anode and Hydrogen is released at the cathode.

In one water molecule (H₂O), two hydrogen atoms and one oxygen atom are present.

So during electrolysis Hydrogen and Oxygen are released in 2:1 ratio by volume.

Since more volume of hydrogen is produced, we see more bubbles in Cathode beaker.
