Abstract
A recently introduced course at Richard Stockton College focuses on modeling chemical processes in seawater aquaria and illustrates to the students chemical principles such as mass and charge balance in solution, acid-base equilibria, and chemical kinetics. This paper describes three exercises from the course, which can be used in a variety of undergraduate chemistry curricula. They are (i) determining the salts and their amounts needed to prepare a given volume of artificial seawater, (ii) modeling aqueous carbonate equilibria, to calculate pH and alkalinity shifts through additions of chemicals, and (iii) modeling chemical kinetics involved in aqueous ozone-bromine reactions, to predict the type and extent of disinfection by-products. The approaches and items for discussion are described for each exercise. The exercises can be used independently of each other, as applications of chemical principles that are being discussed. Several practical examples using empirical data from large aquarium facilities are given to demonstrate how the models can be used.
