Answer 2

2 H₂O(l) → 2 H₂(g) + O₂(g) is the balanced half cell iconic equation for the liberation of oxygen gas when dilute acid is electrolyzed​.

Electrolysis can be used to divide water into hydrogen and oxygen gas. Acids are commonly used to raise the hydrogen ion concentration in a solution. The following are the responses:

Cathode (reduction): 2 H₂O (l)  + 2e⁻  → H₂ (g) + 2 OH⁻ (aq)

Anode (oxidation): 2 OH⁻(aq)  → $\frac{1}{2}$  O₂ (g) + H₂O (l)  + 2 e−

The overall disintegration of water into oxygen and hydrogen is the same when either half-reaction pair is combined:

Overall reaction: 2 H₂O(l) → 2 H₂(g) + O₂(g)
