The use of the p K a rule to predict cocrystal formation is based on the fact that a cocrystal can be distinguished from a salt by whether a proton transfer has occurred from an acid to a base. The p K a describes the tendency of an acid, or a conjugate acid of a base, to give up a proton. It has been suggested that a Δp K a [p K a …
