Determination of Chemical Oxygen Demand (COD) in Water (Potassium Permanganate Method)

Posted by on 8.5.24 in 化学, Onsite

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

Determination of Relative Molecular Mass of Glucose by Freezing Point Depression Method

Posted by on 8.5.24 in 化学, Onsite

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.
