This experiment describes the construction of a simple apparatus for effecting the electrodeposition of nickel onto a tared copper electrode. Results are compared to the determination of nickel by the classical gravimetric […]
Students determine the amount of cranberry juice (as a volume percent) in mixtures of cranberry juice and apple juice by measuring the absorption of mixtures and comparing to a calibration curve prepared […]
Food storage containers may contain micro-particles of Ag, which serves as an anti-microbial agent to limit the growth of molds, fungi, and other microorganisms. Students study the leeching ability of three solvents […]
Using a flatbed scanner to measure the reflectance from samples of a white polyester fabric impregnated with linseed oil, students determine detergent efficiency. Scans of samples are stored as RGB (red, green, […]
Students determine the concentration of sodium sesquicarbonate in an alkaline laundry detergent though a combination of an acid-base titration and thermal gravimetry, both of the thermal decomposition and the decomposition by reaction […]
This experiment uses a novel approach to introduce students to the method of standard additions. To approximate the contribution of shell fragments in sand collected from a beach (in this case, from […]
This experiment describes a quantitative UV-Vis analysis of mixtures of diesel/ethanol and diesel/biofuel based on the absorption of a solvochromatic probe dye. Students first synthesize the dye and then monitor the change […]
In this experiment students complete four tasks: monitoring the production of biodiesel by a transesterification of a commercial oil; quantifying mixtures of biodiesel and petroleum-based diesel; using a Karl-Fisher titration to determine […]
What happens if an institution does not have a quantitative analysis course? Where are students introduced to the concepts of analytical chemistry and the importance of analytical measurements? This post describes how […]
