Acid bases and salts
Which compound is mainly obtained in chloralkali process? Write the balanced equation involved in this process. Name the products obtained at cathode and anode
Sodium hydroxide or Caustic Soda (NaOH) is mainly obtained in chloralkali process.
The balanced equation is as follows:
2NaCl (aq) + 2 H20 (l) -> 2NaOH (aq) + Cl2 (g) + H2 (g)
At the anode (A), chloride (Cl−) is oxidized to chlorine.
At the cathode (C), water is reduced to hydroxide and hydrogen gas.
