Sodium hydroxide is manufacture by the electrolysis of brine solution. The react
Sodium hydroxide is manufacture by the electrolysis of brine solution. The reaction by-products are:
- A. \( C l_{2} \) and \( H_{2} \)
- B. \( C l_{2} \) and \( \mathrm{Na}-\mathrm{Hg} \)
- C. \( C l_{2} \) and \( \mathrm{NaC} \)
- D. \( C l_{2} \) and \( O_{2} \)
Step-by-step solution
In the electrolysis of brine (aqueous NaCl), chlorine gas (Cl2) is produced at the anode and hydrogen gas (H2) is produced at the cathode, while sodium hydroxide (NaOH) remains in solution. Therefore, the by-products are Cl2 and H2.
