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 the above statements, choose the most appropriate answer from the options given below :
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 the above statements, choose the most appropriate answer from the options given below :
Multiple Choice Options
- 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)
Step-by-Step Verified Solution
(A) Aluminium is reactive metal so Aluminium is extracted by electrolysis of Alumina with molten mixture of Cryolite
(B) Cryolite, Na3AlF6
Here, Al is in +3 O.S.
So, answer is (d).
(B) Cryolite, Na3AlF6
Here, Al is in +3 O.S.
So, answer is (d).
