a. For a generic weak monoprotic acid, HA, write out the acid dissociation equilibrium as well as the expression for Ka.
b. Write out the equilibrium that results when a salt solution of the conjugate base of this acid is dissolved in water. What is the equilibrium constant expression for this situation?
c. The two equilibrium constants in parts a and b are related. Using the similarities in the equilibrium constant expressions, derive the relationship.
