Equilibrium Question 361
Question: The values of dissociation constants of some acids (at $ 25^{o}C $ ) are as follows. Indicate which is the trongest acid in water [MP PMT 1991]
Options:
A) $ 1.4\times {10^{-2}} $
B) $ 1.6\times {10^{-4}} $
C) $ 4.4\times {10^{-10}} $
D) $ 4.3\times {10^{-7}} $

Correct Answer: A
Solution:
More is $ K_{a} $ , lesser is $ pK_{a},(pK_{a}=-\log K_{a}) $ more is acidic strength.
