STATEMENT-1 : Zinc and not copper is use...

STATEMENT-1 : Zinc and not copper is used in the recovery of silver from the complex `[Ag(CN)_(2)]^(-)`
and
STATEMENT-2 : Zinc is more powerful oxidising agent than copper.

A

Assertion and Reason both are correct statements and reason is the correct explanation of the assertion.

B

Assertion and Reason both are correct statements, but reason is not the correct explanation of the assertion.

C

Assertion is true, but reason is false.

D

Assertion is false, but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Zinc can easily substitute silver from `[Ag(CN)_2 ]^(-)` while copper cannot do that. Thus, both assertion and reason are correct statements and reason is the correct explanation of the assertion.
