Question

F2 gas cannot be obtained by the electrolysis of any aqueous fluoride salt because

Answer: A

💡 Solution & Explanation

Fluorine gas (F2) is the strongest known oxidizing agent, which means the fluoride ion (F^-) has the lowest oxidation potential. In an aqueous solution, water is oxidized to oxygen gas at a much lower potential than is required to oxidize F^- to F2. Thus, water oxidizes preferentially. Therefore, correct answer is A.
