(1 Point)
In cathode oxygen and in anode hydrogen in the ratio of 2:1
In anode hydrogen and in cathode of oxygen in the ratio of 2:1
In cathode hydrogen and in anode oxygen in the ratio of 2:1
In anode Oxygen and in cathode hydrogen in the ratio of 2:1​

Answer 1

Answer:

In cathode hydrogen and in anode oxygen in the ratio of 2:1

Explanation:

Oxygen will collect at the positively charged electrode (anode) and hydrogen will collect at the negatively charged electrode (cathode). Note that hydrogen is positively charged in the H2O molecule, so it ends up at the negative electrode. (And vice versa for oxygen.)
