Question

The electrolytic method of reduction is employed for the preparation of metals that
(a) are weakly electropositive
(b) are moderately electropositive
(c) are strongly electropositive
(d) form oxides

Answer 1

Strongly Electropositive

highly reactive

Answer 2

The electrolytic method of reduction is employed for the preparation of metals that (c) is strongly electropositive.

• Electrolytic reduction is a method used for the purification of different metals based on their electropositive character.
• Examples of metals that can undergo electrolytically reduction are calcium, aluminium and magnesium.
• It is used for metals for which reduction in an aqueous medium is difficult.
• The metals are highly electropositive because they have a low reduction potential. as they have low reduction potential they can easily give electrons to become positively charged species cation.
