k(b(1)) of N(2)H(4) is 4xx10^(-6) .Then ...

`k_(b_(1))` of `N_(2)H_(4)` is `4xx10^(-6)` .Then what is the acid dissociation constant of `N_(2)H_(5)^(+)` and `N_(2)H_(6)^(+)` respectively?

A

data insufficient `4xx10^(-6)`

B

data insufficient `2.5xx10^(-8)`

C

`2.5xx10^(-9)` Data insufficient

D

`2.5xx10^(-9),4xx10^(-6)`

Text Solution

Verified by Experts

`K_(a_(1))=(K_(w))/(K_(b_(1)))=(10^(-14))/(4xx10^(-6))=2.5xx10^(-9)`
`K_(b_(2))` data not given so `K_(b_(2))` cannot be determined.
