Chlorine is typically manufactured by the electrolysis of brine.

  • Electrolysis of brine also generates hydrogen and sodium hydroxide

  • Known as co-products

\begin{gather} 2Cl^{-}\Rightarrow Cl_{2}+2e^{-}{} \\ 2H_{2}O+2e^{-}\Rightarrow 2OH^{-}+H_{2}{} \\ 2Cl^{-}+2H_{2}O\Rightarrow Cl_{2}+2OH^{-}+H_{2}{}\\ \end{gather}
