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
