True
Explanation:
The half reaction, balanced with acid, is: Reduction at cathode: 2 H+(aq) + 2e− → H2(g) At the positively charged anode, an oxidation reaction occurs, generating oxygen gas and giving electrons to the anode to complete the circuit:
The number of hydrogen molecules produced is thus twice the number of oxygen molecules.
