A concentrated aqueous solution of sodium iodide is electrolysed with platinum electrodes. The solution contains the ions $\text{Na}^+$, $\text{I}^-$, $\text{H}^+$ and $\text{OH}^-$. During this electrolysis, to which electrodes are these ions attracted?
- Acathode: $\text{H}^+$ and $\text{Na}^+$ / anode: $\text{I}^-$ and $\text{OH}^-$
- Bcathode: $\text{H}^+$ and $\text{OH}^-$ / anode: $\text{I}^-$ and $\text{Na}^+$
- Ccathode: $\text{I}^-$ and $\text{Na}^+$ / anode: $\text{H}^+$ and $\text{OH}^-$
- Dcathode: $\text{I}^-$ and $\text{OH}^-$ / anode: $\text{H}^+$ and $\text{Na}^+$
