Assertion (A) CuI(2) cannot be prepared ...

Assertion (A) `CuI_(2)` cannot be prepared by the reaction of `Cu^(2+)` (aq) with `I^(-)` (aq)
Reason ( R) Aqueous `Cu^(2+)` solution is blue in colour
The correct answer is

A

Both (A) and ( R) are correct and ( R) is the correct explanation of (A)

B

Both (A) and ( R) are correct but ( R) is not correct explanation of (A)

C

(A) is correct but ( R) is not correct

D

(A) is not correct but ( R) is correct

Text Solution

Verified by Experts

The correct Answer is:
B
The reaction of `Cu^(2+)` with `I^(-)` has negative cell potential thus it is not possible.
Reduction `2Cu^(2+)(aq)+2e^(-)to2Cu^(+)(aq),E=+0.159`
Oxidation `2I^(-)toI_(2)+2e^(-),E=-0.535`
