MCQs Quiz

Non-aqueous titrations are essential in pharmaceutical analysis for determining weak acids and bases that are insoluble or poorly ionized in water. Choosing the right solvent—glacial acetic acid, methanol, DMF, pyridine or mixtures—controls ionization, indicator response and titrant behavior. Key solvent properties include protic vs. aprotic character, dielectric constant, donor/acceptor numbers and autoprotolysis. Common titrants are … Read more
