Question

Electrolytie reduction process is used for the extraction of:

• A. alkali metals
• B. alkaline earth metals
• C. aluminium
• D. all of these

Answer 1

The correct option is D all of these

This process is mainly used for the extraction of highly electropositive metals. Electrolysis is carried out in a large cell and a small amount of another suitable electrolyte is added which

(i) Lowers the melting point of the main electrolyte

(ii) Enhances its conductivity

(iii) Reduces corrosion troubles

eg: $Na,K,Mg,Ca,Al,$ etc.
