Unionization

Still, the coffee giant, which has been facing a wave of unionization efforts inside stores across the United States, was light on specifics around some of the concerns that have been raised by its employees, like scheduling.

In this case, the dissociation of the acid and unionization (or hydrolysis) of conjugate salt should be taken into account for calculating [H⁺] [i.e., Equation (2.39)].

The acid or base form is the unionized form and salt form is the ionized form of the corresponding acid or base. Accordingly, ionized and unionized can be substituted in the above equations in order to calculate the amount of ionization or unionization at a particular pH value.

Unionization (lipid solubility) facilitates absorption whereas ionization (water solubility) facilitates excretion of drug.
