A two-dimensional chart for the classification of the main classes of inorganic compounds is presented. This presentation takes advantage of the visual memory of high school students in learning the relationship between acidic and basic properties of compounds. With a limited use of introductory vector algebra, the chart makes it possible to predict reaction products and figure out the coefficients in chemical equations of acid–base reactions.
Supplement
Various examples that demonstrate how to figure out stoichiometric coefficients for acid–base reactions and even to predict possible reaction products are available.
The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
