Acetic acid ch3cooh is one of the simplest carboxylic acids

Question

1. Acetic acid (CH₃COOH) is one of the simplest carboxylic acids. It is an important chemical reagent and industrial chemical. Vinegar is dilute acetic acid, often produced by fermentation. The following is a reversible reaction:

CH₃COOH ↔ H⁺ + CH₃COO^-

a. Write the set up you would use to calculate the K_a of this reaction.

b. Calculate the hydrogen ion concentration [H⁺] of a 0.1 M solution of acetic acid given that the dissociation constant of acetic acid is K_a = 1.8 x10^-5. Work must be shown in order to earn credit.
