| Module objectives/intended learning outcomes | Upon completing the course through experimental methods, students are capable of analyzing and drawing conclusions about the relationship between measured variable data and dependent variable data based on experimental results.Upon completing laboratory practical activities, students are capable of demonstrating responsibility in conducting accurate and precise measurements of variables (such as temperature, pressure, heat or energy, rate, and other physical properties) in the laboratory.Upon completing laboratory practical activities, students are capable of performing measurements of key variables (such as temperature, pressure, heat or energy, reaction and flow rate, viscosity, acidity, conductivity, surface tension, adsorption, etc.) to accurately and correctly analyze the relationship between these variables and other dependent variables. |
| Content | This course is designed to strengthen students’ ability to conduct practical works of Physical Chemistry and the following topics are covered by the course: Thermochemistry Measures reaction enthalpy using a calorimeter. Activities include calibrating the calorimeter and calculating heat changes for reactions like neutralization and metal displacement. Synthesis and Characterization of CQDs Students perform synthesis of CQDs using different biomass sources and characterize the optical properties of the CQDs. Students also estimate the energy gap of the CQDs using Tauc Plot Surface Tension Measures liquid surface tension using capillary rise and drop methods, focusing on molecular interactions at interfaces. Viscosity and Activation Energy Examines liquid viscosity using Ostwald and Hoppler methods, analyzing temperature effects and calculating activation energy for flow. Solubility and Temperature Studies temperature’s impact on solubility, using titration and Van’t Hoff analysis to calculate dissolution enthalpy. Activation Energy of Reactions Determines activation energy for sodium thiosulfate-hydrogen peroxide reaction using Arrhenius plots. Reaction Order in Saponification Confirms second-order kinetics in ethyl acetate saponification, analyzing reaction rates over time. Emulsion Demulsification Investigates emulsion breakdown by altering interfacial tension, emphasizing applications in food and industrial processes. |
