Vedclass · Answer

(B) In the chlor-alkali process,an aqueous solution of sodium chloride (brine) is electrolyzed. The chemical reaction is: $2NaCl(aq) + 2H_2O(l) \rightarrow 2NaOH(aq) + Cl_2(g) + H_2(g)$. At the anode,chloride ions are oxidized to form chlorine gas $(Cl_2)$. At the cathode,water molecules are reduced to form hydrogen gas $(H_2)$ and hydroxide ions $(OH^-)$. Therefore,$H_2$ gas is produced at the cathode.

Which gas is produced at the cathode when $NaOH$ is prepared by the chlor-alkali process?
