The Softening of Hard Water and Complexometric Titrations: An Undergraduate Experiment Helena Ceretti, Enrique A. Hughes, and Anita Zalts
An experiment in which (i) water hardness is explained and demonstrated; (ii) ion-exchange resin properties are visually demonstrated and then used for softening water; (iii) complexometric titrations are used for evaluating water hardness before and after softening; and (iv) acid-base titration can be used to show that the Ca/Mg ions removed by the ion exchanger are replaced by H ions.

Integrating High School Chemistry with Environmental Studies and Research Jack Randall
This article is a summary of a presentation made at the 1996 BCCE in Clemson, SC, as part of a symposium detailing the integration of environmental topics into Chemistry curricula. High school chemistry has long used environmental topics to enhance the study of various components of the curriculum. This article illustrates the benefits of incorporating environmental science as an integral part of a high school Chemistry course.

A study of water pollution. An undergraduate chemistry laboratory experience Sarkis, Vahak D.
In addition to its environmental relevance, a water pollution study of the inorganic constituents in water as outlined in this article, provides the student with certain important principles of chemistry namely, colorimetric and titrimetric procedures.

The effervescence of ocean surf Plumb, Robert C.; Blanchard, Duncan C.; Bilofsky, Howard S.; Bridgman, Wilbur B.
A pure liquid will not foam, but all true solutions will, as dictated by the fundamental concepts of surface thermodynamics enunciated by Gibbs.
