Concentrated aqueous sodium chloride is electrolysed with inert electrodes. Which equation represents the correct ionic half-equation for the reaction at the anode?
- A$\text{Cl}^- + e^- \rightarrow \text{Cl}$
- B$2\text{Cl}^- \rightarrow \text{Cl}_2 + 2e^-$
- C$\text{H}^+ \rightarrow \text{H} + e^-$
- D$2\text{H}^+ + 2e^- \rightarrow \text{H}_2$
