The percentage of pyridine (C_5H_5N) that forms pyridinium ion (C_5H_5N^(+)H) in a 0.1 M aqueous pyridine solution (K_b for C_5H_5N=1.7xx10^(-9) ) is

The percentage of pyridine (C_5H_5N) that forms pyridinium ion (C_5H_5

1.	The percentage of pyridine (C_5H_5N) that forms pyridinium ion (C_5H_5N^(+)H) in a 0.1 M aqueous pyridine solution (K_b for C_5H_5N=1.7xx10^(-9) ) is
Answer» `0.77%` `1.6%` `0.006%` `0.013%` SOLUTION :Pyridine `(C_5H_5N)` is a WEAK BASE, `K_b=C alpha^2` `alpha=sqrt((1.7xx10^(-9))/0.1)=1.30xx10^(-4)` `%alpha=1.30xx10^(-4)XX100` `%alpha`=0.013%
