Ionization constants of weak acids, PH of weak acids

Question

Statement I : Benzoic acid (Ka = 6.5×10^–5) is stronger acid than acetic acid (Ka = 1.74×10^–5).
Statement II : Larger the value of K_a, greater is the acidity.

Easy

A

Statement I and II are correct
B

Statement I is correct and Statement II is incorrect
C

Statement - I is incorrectand Statement II is correct
D

Both statement - I and statement - II are False

Solution

'Ka' is also known as dissociation constant. Higher the dissociation constant, higher will be the presence of H⁺ and so greater acidity
