Question

The process of electrolysis is used for obtaining such metals which are

• A. Moderately reactive.
• B. Highly reactive.
• C. Highly unreactive.
• D. Less reactive

Answer 1

The correct option is B Highly reactive.

Electrolysis is the process by which electric current is passed through a substance to effect a chemical change. Oxides of highly reactive metals cannot be reduced with the help of carbon as it is less reactive than them. Such highly reactive metals are obtained by the electrolysis of molten salts generally chlorides or oxides. The metal obtained after electrolysis is comparatively pure as compared to other methods.
