Acetic acid and propionic acid have K(a)...

Acetic acid and propionic acid have `K_(a)` values `1.75xx10^(-5)` and `1.3xx10^(-5)` respectively at a cetrain temperature. An equimolar solution of a mixture of the two acids is partially neutralised by NaOH. How is the ratio of the contents of acetate and propionate ions related to the `K_(a)` values and the molarity ?

A

`((alpha)/(1-alpha)) = (1.75)/1.3 xx ((beta)/(1-beta))`, whereas `alpha and beta` are ionized fractions of the acids

B

The ratio is unrelated to the `K_(a)` values

C

The ratio is unrelated to the molarity

D

The ratio is unrelated to the pH of the solution.
