Question

Electrolytic reduction process is used for the extraction of

• A. highly electronegative metals.
• B. highly electropositive metals.
• C. transition metals.
• D. noble metals.

Answer 1

The correct option is B

highly electropositive metals.

• Arrangement of the metals on the basis of their reactivity towards other elements is termed as reactivity series. Elements at the top of this series are comparatively more reactive than elements below in the series.
• Electrolysis or electrolytic reduction is the process in which metal is extracted by passing electricity to the aqueous or molten solution of any metal and compound.
• Metals present at the top of reactivity series like Sodium (Na) and Magnesium (Mg) can not be obtained by heating its oxide in presence of a reducing agent (like Carbon (C)). Hence, electrolysis is done to extract these metals.
• In the reactivity series, metals at the peak of the series are highly electropositive in nature.

Hence, option B is correct. Highly electropositive metals are extracted by the electrolytic reduction process.
