Titrimetrically or potentiometrically as given in Table 5. Analytical methods for venlaflaxine hydrochloride and metabolites determinations in different matrices. When a weak base, such as pyridine, is dissolved in acetic acid, the acetic acid exerts its levelling effect and enhances the basic properties of the pyridine. Pyridine, a weak base, when dissolved. Q. Non-aqueous titration is based on which theory? Procedure: Gradually mix 8. We need non aqueous titration because weak acid & weak bases are when dissolved in water they don't get completely ionise due to their less tendencie toward ionisation, but when we use non aqueous solventit is strongly acidic in nature or basic in nature. Vorlander first proposed the non-aqueous titration method that is titration of aniline with the HCl in non-aqueous solvent, that is, benzene. Water molecules compete with various bases and acids dissolved in them for proton donation and acceptance.

Materials Required: Ethosuximide: 0. 3) A non-aqueous solvent may help two are more acids in mixture. They have a levelling effect on weak acids due to their significant proton affinity. Organic acids and bases that are insoluble in water are soluble in a non-aqueous solvent and can be titrated by non-aqueous titration. In general, the reaction taking place between a primary. 6 gm of anhydrous KOH in 1000 ml of anhydrous methanol.
