Vedclass · Answer

(A) Brine is an aqueous solution of sodium chloride $(NaCl)$.During the electrolysis of brine, the ions present are $Na^{+}$, $Cl^{-}$, $H^{+}$, and $OH^{-}$.At the anode, oxidation occurs. Between $Cl^{-}$ and $OH^{-}$ ions, $Cl^{-}$ ions are preferentially oxidized to form chlorine gas due to their lower discharge potential in concentrated solutions.The reaction at the anode is: $Cl^{-}_{(aq)} \rightarrow \frac{1}{2} Cl_{2(g)} + e^{-}$.

In the preparation of chlorine by the electrolysis of brine, the reaction taking place at the anode is
