Assertion: If a strong acid is added to ...

Assertion: If a strong acid is added to a solution of potassium chromate it changes its colour from yellow to orange.
Reason: The colour change is due to the oxidation of potassium chromate.

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 explantion of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(yellow)(2CrO_(4)^(2-))overset(H^(+))rarr underset(orange)(Cr_(2)O_(7)^(2-))`
`Cr` in `+6` state.
