Ionized or unionized
WebAnswer: a Explanation: The pH-partition hypothesis tells that for drug compounds with molecular weight more than 100, that are transported by passive diffusion across the cell membrane, the process is governed by the capability of lipid solubility of unionized drugs, the dissociation constant of the drug and pH at the absorption site.
