Question

The two metals which are extracted by means of electrolytic reduction of their molten salts are ______.

Options

• magnesium and manganese

• iron and aluminium

• zinc and magnesium

• magnesium and aluminium

Answer 1

The two metals which are extracted by means of electrolytic reduction of their molten salts are magnesium and aluminium.

Explanation:

Magnesium and aluminium are highly reactive metals placed near the top of the reactivity series, meaning their oxides are extremely stable and cannot be reduced by carbon. Consequently, they must be extracted by electrolytic reduction of their molten salts (e.g., molten chloride for magnesium and molten oxide for aluminium) to obtain pure metal.
