Students are asked to develop a procedure for the determination of the amount of ascorbic acid in fresh and boiled cabbage tissue. In order to accurately determine the ascorbic acid content, students must take into consideration the following: a representative sample, aliquots, the boiling procedure, the presence of the enzyme ascorbic acid oxidase, and the release of ascorbate into the boiling water.

This is an activity (located on page 3 of the PDF) about the use of reduction agents to decontaminate ground water. Learners will conduct a reduction-oxidation (redox) reaction in which vitamin C acts as a reduction agent after passing through a model of top soil, sand, and gravel to "pollutants" (starch-iodine mixture). This simulates how nanoparticles of iron are being used to detoxify water under former factory sites. Relates to linked video, DragonflyTV Nano: Water Clean-up. (less)
