Ionized or unionized
WebNeutral or unionized compounds can be extracted from aqueous solutions while ions cannot. When a drug exists in its ionized form, it can be converted to the unionized form by altering the pH of the medium in which the drug is contained. 1. Partition coefficient as a function of pH. Many drugs are acids or bases that dissociate in aqueous solution.
