QUESTION:

A 0.148 M solution of a monoprotic acid has a percent ionization of 1.55%. Determine the acid ionization constant (Ka) for the acid.

ANSWER:

Problem 75EA 0.148 M solution of a monoprotic acid has a percent ionization of 1.55 %. Determine theacid ionization constant for the acid. Step by step solutionStep 1 of 3Let be the weak monoprotic acid.From the given,The initial concentration of the monoprotic acid = 0.148 MThe percent dissociation (or the percent ionization) = 1.55 %.Let’s calculate the concentration of ion at equilibrium using the formula of percentionization as follows.
