Which one of the following correctly shows the weak acid equilibrium for trichloroacetic acid, CCl₃COOH?
Answers
Explanation:
titrant, or in our case, the volume of a strong base plotted against the pH. There are several characteristics that are seen in all titration curves of a weak acid with a strong base.
Answer:
When an uncharged weak acid is added to water, a homogeneous equilibrium forms in which aqueous acid molecules, HA(aq), react with liquid water to form aqueous hydronium ions and aqueous anions, A-(aq). The latter are produced when the acid molecules lose H+ ions to water.
HA(aq) + H2O(l) H3O+(aq) + A-(aq)
In writing an equilibrium constant expression for this homogeneous equilibrium, we leave out the concentration of the liquid water. The equilibrium constant for this expression is called the acid dissociation constant, Ka.
= acid dissociation constant
