Question

Name one metal each which is extracted by:
(a) reduction with carbon. (b) electrolytic reduction.
(c) reduction with aluminium (d) reduction with heat alone.

Answer 1

Let us name one metal in each of the following cases:

(a) Reduction with carbon: Zinc is a moderately reactive metal and thus, its oxide is reduced by carbon.

(b) Electrolytic reduction: Sodium is a highly reactive metal and it cannot be reduced by carbon or aluminium. Thus, it is reduced by electrolysis.

(c) Reduction with aluminium: Manganese is a reactive metal and it cannot be reduced by carbon. Thus, it is reduced by aluminium.

(d) Reduction with heat alone: Mercury is a least reactive metal and thus, it is reduced on heating alone
