medium

At $298\,K$ a $0.1 \,M $ $C{H_3}COOH$ solution is $ 1.34\%$ ionized. The ionization constant ${K_a}$ for acetic acid will be

A

$1.82 \times {10^{ - 5}}$

B

$18.2 \times {10^{ - 5}}$

C

$0.182 \times {10^{ - 5}}$

D

None of these

Solution

(a)$K = c{\alpha ^2} = 0.1 \times {\left( {\frac{{1.34}}{{100}}} \right)^2} = 1.8 \times {10^{ – 5}}$.
