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 $\mathrm{Al}_2 \mathrm{O}_3$ with cryolite.
Reason (R): The oxidation state of AI in cryolite is +3 .
In the light of the above statements, choose the most appropriate answer from the options given below:
Select the correct option:
A
(A) is true but (R) is false
B
(A) is false but (R) is true.
C
Both (A) and (R) are correct and (R) is the correct explanation of (A)
D
Both (A) and (R) are correct but (R) is not the correct explanation of (A)
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
(A) Aluminium is reactive metal so Aluminium is extracted by electrolysis of Alumina with molten mixture of Cryolite
(B) Cryolite, $\mathrm{Na}_3 \mathrm{AlF}_6$ Here Al is in +3 O.S.
So Answer is 4
