Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Aluminium is extracted from bauxite by the electrolysis of molten mixture of Al2O3 with cryolite. Reason (R) : The oxidation state of Al in cryolite is +3. In the light of above statements, choose the most appropriate answer from the options given below :

1. (A) is true but (R) is false
2. (A) is false but (R) is true
3. Both (A) and (R) are correct and (R) is the correct explanation of (A)
4. Both (A) and (R) are correct but (R) is not the correct explanation of (A)

Correct answer: Both (A) and (R) are correct but (R) is not the correct explanation of (A)

Solution

The extraction of aluminium from bauxite through electrolysis is indeed correct, as stated in the assertion. However, the reason provided about the oxidation state of aluminium in cryolite does not directly explain the process of aluminium extraction, making it a true statement but not a correct explanation.
