Primary and Secondary Standards Solutions: Quantitative chemical analysis is one of the most important aspects of pharmaceutical analysis and analytical chemistry. In volumetric analysis or titration methods, accurate determination of concentration is essential for obtaining reliable analytical results. To achieve this accuracy, solutions of known concentration called standard solutions are used. Standard solutions are solutions…
Methods of Expressing Strength of Solutions: Solutions are homogeneous mixtures in which one or more substances, known as solutes, are dissolved in another substance called the solvent. In pharmaceutical sciences, chemistry, pharmacology, and clinical practice, solutions are extensively used for preparing medicines, reagents, injections, syrups, ophthalmic preparations, and laboratory formulations. The therapeutic efficacy and safety…
Pharmaceutical Analysis: Pharmaceutical analysis is one of the most important branches of pharmaceutical sciences. It deals with the identification, determination, separation, purification, and quantification of chemical substances used in the preparation of medicines and pharmaceutical products. The quality, purity, safety, and efficacy of pharmaceutical products depend greatly upon accurate analytical evaluation. Therefore, pharmaceutical analysis plays…
