Assertion : Aluminium is used as a reducing agent in the extraction of chromium from its oxide `(Cr_(2)O_(3))`.
Reason : Reduction by aluminium is known as Gold Schmidt thermite process or aluminothermite process.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

IF both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
b
Aluminium has a great affinity for oxygen. It acts as a reducing agent when the metal having high m.pt. is to be extracted from its oxide.
`Cr_(2)O_(3) + 2Al to 2Cr + Al_(2)O_(3)`
