Non-Aqueous Titration of Basic Substances
• Analyte: Very weak basic substances including aliphatic and
aromatic amines (such as adrenaline), alkaloids (such as atropine ,
quinine , nicotine , caffeine , codeine and cocaine) and alkali salts
of weak acids (such as sodium benzoate , sodium salicylate ,
diclofenac sodium and saccharin sodium).
• Solvent: Glacial acetic acid. Acetic anhydride is added to remove any
water that may be present in the medium.
