During the electrolysis of cryolite, aluminium and fluorine are formed in ........ molar ratio :
- A \(1: 2\)
- B \(2: 3\)
- C \(1: 1\)
- D \(1: 3\)
Answer & Solution
Correct Answer
(B) \(2: 3\)
Step-by-step Solution
Detailed explanation
Electrolysis of cryolite can be explained as \(\mathrm{Na}_3 \mathrm{AlF}_6 \rightleftharpoons 3 \mathrm{NaF}+\mathrm{AlF}_3\) \(4 \mathrm{AlF}_3 \rightleftharpoons 4 \mathrm{Al}^{3+}+12 \mathrm{~F}^{-}\)…
