Pharmaceutical Analysis is a fundamental subject in B.Pharmacy that deals with the identification, determination, and quality evaluation of drugs and pharmaceutical substances. It includes classical analytical techniques such as volumetric, gravimetric, and electrochemical methods. The subject covers preparation and standardization of solutions, methods of expressing concentration, and the use of primary and secondary standards. It also explains sources and types of analytical errors, accuracy, precision, and significant figures. Various titrimetric methods including acid–base, non-aqueous, precipitation, complexometric, redox, and diazotisation titrations are studied. Electrochemical techniques like conductometry, potentiometry, and polarography ensure accurate drug analysis and quality control.
