Electrolysis of fused NaCl will give

Options

  1. ANa
  2. BNaOH
  3. CNaClO
  4. DNaClO ₃

Correct answer

A. Na

Step-by-step solution

When molten or fused NaCl is electrolysed, it yields metallic sodium and gaseous chlorine. Industrially, this process is called Down's process. Reactions occurring in Down's cell are as follows array rlr NaCl (l) & Na ⁺+ Cl ⁻ & Na ⁺+e⁻ & Na & (at cathode) Cl ⁻ & 1 2 Cl ₂+e⁻ (at anode) array
