Question

electrolytic process is the convenient method to extract more reactive metal justify the statement​

Answer 1

Answer:

Metals of high reactivity; such as sodium, calcium, magnesium, aluminium, etc. are extracted from their ores by electrolytic reduction. These metals cannot be reduced using carbon because carbon is less reactive than them.

Electrolytic Reduction: Electric current is passed through the molten state of metal ores. Metal; being positively charged; is deposited over the cathode.

Example: When electric current is passed through molten state or solution of sodium chloride, sodium metal deposited over cathode.

Na+ + e− ⇨ Na

2Cl− − e− ⇨ Cl2

2NaCl ⇨ 2Na + Cl2

Metals obtained from the process of electrolytic reduction are pure in form.
