Carnallite on electrolysis gives
Options
(a) Ca and Cl₂
(b) Na and CO₂
(c) Al and Cl₂
(d) K and Cl₂
Correct Answer:
K and Cl₂
Explanation:
Carnallite is an ore of potassium: KCl.MgCl₂.6H₂O. Electrolysis of fused KCl and CaCl₂ is carried out to obtain potassium. KCl ⇌ K⁺ + Cl⁻. At cathode, K⁺ + e⁻ → K. At anode, 2Cl⁻ → Cl₂ + 2e⁻.
