The percentage of pyridine (C H N) that forms pyridinium ion (C H N H) in a 0.10 M aqueous pyridine solution ( b K for C H N 1.7 10 ) x is (NEET 2016)
A.0.013 %✓ Correct
B.0.77 %
C.1.6 %
D.0.0060 %
Explanation
We know that pyridine is a base. Therefore, its reaction in water as follows- 5 5 2 5 5 2 b b 9 4 C H N H O C H NH OH K C K / C 1.7 10 / 0.1 1.30 10 100 0.013% -> x x x
