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 $C_5H_5N$ = $1.7 imes 10^{-9}$) is

Question

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 $C_5H_5N$ = $1.7 	imes 10^{-9}$) is

[Solution] $\alpha = \sqrt{K_b/c} = \sqrt{1.7 	imes 10^{-8}} = 1.3 	imes 10^{-4}$ = 0.013%. Answer (2).
