Students calculate the pH of various situations for polyprotic systems. There is also an accompanying text that explains the answers to the problems.
Active Learning Resources
Browse resources, explore categories, and discover materials contributed to the ASDL library.
In this activity, students are given an analysis problem and asked to develop plans for sampling and sample preparation.
Students learn to:
Explain the purpose of using internal standards
Use response factors to calculate an unknown concentration based on an internal standard
Determine the limits of detection (LOD) and quantification of a method.
Identify basic decisions associated with performing a chemical analysis.
This activity is designed to give students the ability to: Accurately and effectively navigate the scientific literature. Get information from a journal article. Jennifer Esbenshade, University of Tennessee Martin (jesbensh@utm.edu)
