The Ratio of Specific Heats of a Gas
Location: PL2 Newton Lab Instructor: Zehao, Pan Instructions: A cylinder is filled with air and a Pressure Sensor is attached. The piston is plucked by hand and allowed to oscillate. The oscillating pressure is recorded as a function of time and the period is determined. The ratio of specific heat capacities is calculated using the period of oscillation, according to Ruchhardt’s method. Equipment: Heat engine/gas law apparatus, large rod stand, 45 cm long steel rod,...
Compound Pendulum

Determination of Chemical Oxygen Demand (COD) in Water (Potassium Permanganate Method)
Location: CL 2 Mendeleev Lab Instructor: Yunjuan, Zhang Instructions: The level of Chemical Oxygen Demand (COD) in water is one of the important indicators of water quality pollution. It is a parameter that is frequently measured in environmental protection and water quality control. COD refers to the milligrams of oxygen consumed when reducing substances in 1 liter of water are oxidized under specific conditions. Equipment: None Lab Manual

Location: CL 1 Dalton Lab Instructor: Yunjuan, Zhang Instructions: In this experiment we will record the diffraction peaks of an ionic solid (sodium chloride) and an organic polymer (polystyrene) by X-Ray Diffraction (XRD). Analysis of the data provides insight to the nature of the compounds themselves. Equipment: XRD Manual Analysis of Structure of Sodium Chloride and Polystyrene Using X-Ray Diffration
Determination of Relative Molecular Mass of Glucose by Freezing Point Depression Method
Location: CL 1 Dalton Lab Instructor: Yunjuan, Zhang Instructions: When a solute is dissolved in a solvent, the freezing point of the solvent decreases, which is one of the colligative properties of dilute solutions. The depression of the freezing point of a non-volatile and non-electrolyte dilute solution is directly proportional to the molal concentration of the solution.
