उत्तर

The metal that cannot be obtained by electrolysis of the aqueous solution of its salts is Al.

Explanation:

Aluminium cannot be obtained by electrolysis of its aqueous salt solution because its ion (Al3+) has a very high reduction potential. In aqueous solution, water gets reduced preferentially to hydrogen gas instead of Al3+ being reduced to aluminium metal.
