Question

Dissociation constant (K) of formic acid and acetic
acid are 2.5 x 104 and 0.5 x 10-5 respectively. The
ratio of their relative strengths at the same
concentration is
(1) 2.09
(2) 7.07
(3) 4.26
(4) 6.03
Ans 2​

Answer 1

Answer:

(2)7.07

Explanation:

$\sqrt{ka \div k} b$

√2.5×10^-4/√0.5×10^-5

√5×10

√50 ≈7.07
