The percentage of pyridine `(C_(5)H_(5)N)` that forms pyridinium ion `(C_(5)H_(5)N^(+)H)` in a 0.10 M aqueous pyridine solution (`K_(b)` for `C_(5)H_(5)N=1.7xx10^(-9)`) is

A

6.0E-5

B

0.00013

C

0.0077

D

0.016

Text Solution

Verified by Experts

The correct Answer is:
B
`alpha=sqrt((K_(b))/(C))` ltBrgt `=sqrt((1.7xx10^(-9))/(0.1))`
`=sqrt(1.7xx10^(-8))`
`=1.3xx10^(-4)`
`=1.3xx10^(-2)%`
