Identify the reaction taking place at anode during electrolysis of molten NaCl ?
Options
- A2 OH ⁻ H ₂ O + 1 2 O ₂+2 e ⁻
- B2 H ⁺ 2 e ⁻ H ₂
- CNa ⁺+ le ⁻ Na _ ( s )
- D2 Cl ⁻ Cl _ 2( ~g ) +2 e ⁻
Correct answer
D. 2 Cl ⁻ Cl _ 2( ~g ) +2 e ⁻
Step-by-step solution
At anode oxidation takes place and Cl ⁻ ions get oxidized at anode, 2 Cl ⁻ Cl ₂+2 e ⁻
