Assertion : Solution of Na(2) CrO(4) in ...

Assertion : Solution of `Na_(2) CrO_(4)` in water is intensely electrons.
Reason : Oxidation state of `Cr` in `Na_(2) CrO_(4)` is `+ VI`.

A

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

B

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

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A

A solution of `Na_2CrO_4` in water is intensely coloured due to oxidation state of chromium in `Na_2CrO_4` is + 6. Here both assertion and reason are correct.
