JEE Main Chemistry question

Acetic acid and propionic acid have Ka values 1.75×10⁻⁵ and 1.3×10⁻⁵ respectively at a certain temperature. An equimolar solution of a mixture of the two acids is partially neutralized by NaOH. How is the ratio of the contents of acetate and propionate ions related to the Ka values and the molarity?

• (A)(α/(1−α)) = (1.75/1.3) × (β/(1−β)), where α and β are ionised fractions of the acidsCorrect
• (B)The ratio is unrelated to the Ka values
• (C)The ratio is unrelated to the molarity
• (D)The ratio is unrelated to the pH of the solution
