Assertion: In the solution of K in liqui...

Assertion: In the solution of K in liquid `NH_(3)`, blue colour appears.
Reason: K reacts with `NH_(3)` to form `KNH_(2)`

A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion

B

If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion

C

If Assertion is True but the Reason is False

D

If both Assertion & Reason are False

Text Solution

Verified by Experts

The correct Answer is:
B

`K+NH_(3)("liq")rarr[K^(+)(NH_(3))_(x)]+underset("ammoniate electron")underset("blue color due to")([(e^(-)CNH_(3))_(y)])`
`[K(NH_(3))_(x)]^(+)rarrKNH_(2)+H^(+)`
`H^(+) + e^(-) rarr H`
`H + H rarr H_(2)`
Both are correct
