Question

Calculate the ratio of the degree of dissociation of acetic acid and hydrocyanic acid $\left(HCN\right)$ in $1M$ of their respective solution of acids.

(Given $K_{a({CH}_{3}COOH}=1.8\times {10}^{-5};K_{a\left(HCN\right)}=6.2\times {10}^{-10}$)

Answer 1

$K_a=C{\alpha }^2$
$\frac{{\alpha }_1}{{\alpha }_2}=\sqrt{\frac{{Ka}_1}{{Ka}_2}}=\sqrt{\frac{1.8\times {10}^{-5}}{6.2\times {10}^{-10}}}=170.4/1$
