Abstract

The availability of a variety of bottled waters from a number of sources provides a readily available resource for problem-solving exercises in chemical analysis. Students are challenged to identify water samples using the known chemical analyses of bottled waters. Several common water quality measurements such as hardness, alkalinity, and ion analysis can be used by students to identify the unknown water. This exercise develops problem-solving skills as students become familiar with basic lab techniques, quality control, data interpretation, and standard methods. Throughout the activity students become more conscious of both their data and data obtained from references. Students learn that data reported from a source are not absolute values, and develop varying degrees of confidence in data sources.

      Ion chromatography (IC) is a powerful technique for analysis of aqueous media containing a variety of both cations and anions. It promises to replace classical wet chemical methods for such analyses, which are frequently labor intensive and time consuming ...
