WebAmmonia exists in two forms, namely, unionized (NH3) and ionized (NH4+). Both forms are measured together and are referred to as total ammonia nitrogen (TAN). Most ammonia test kits are actually testing TAN (Total Ammonia Nitrogen). TAN is a combination of unionized ammonia (NH3) and ionized ammonium (NH4+). 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.
