Q. The percentage of pyridine $(C_5H_5N)$ that forms pyridinium ion $(C_5H_5N^+H)$ in a $0.10\, M$ aqueous pyridine solution ($K_b$ for $C_5H_5N = 1.7 \times 10^{-9}$) is

Solution:

$\alpha=\sqrt{\frac{ K _{ b }}{ C }}$

$=\sqrt{\frac{1.7 \times 10^{-9}}{0.1}}$

$=\sqrt{1.7 \times 10^{-8}}$

$=1.3 \times 10^{-4}$

$=1.3 \times 10^{-2} \%$
