specific amount of salicylic acid into the same amount of aspirin that was high in purity. Furthermore, the other objectives were to enable students to conduct the synthesis of aspirin, reinforce skills or recrystallisation and the technique of melting point determination. The amount of each compound should be the same because there is a 1:1 ratio between them. The purity of the synthesized aspirin was measured by determining its melting point and percent yield. Soluble impurities increase the range
INTRODUCTION The human gastrointestinal track is a complex time, position, patient-dependent absorptive, metabolizing, and excretive organ. Key of physiological factors that control absorption of drugs from the GIT include gastric, fluid and food intake, bulk fluid and luminal pH, gastric and intestinal secretions, absorptive mechanisms, enterocyte-based metabolism and secretion. Properties of a drug, such as its solubility, stability, ionization, and lipophilicity, strongly influence the rate and
