Reactions : AcidBaseRxns (20 Variations) In order to answer the following questions, write the net ionic equation for the reaction between equal volumes of 0.10 M solutions of the following acid and base:
KOH(aq) + HBr(aq)
What are the reaction products? Does the reaction yield an acidic, basic, or neutral aqueous solution?
Dynamic Reaction Figures: An Integrative Vehicle for Understanding Chemical ReactionsEmeric Schultz Describes the dynamic reaction figure, a flexible learning tool that can be used to balance chemical equations, predict the results of potential reactions, present the underlying mechanism of reactions, and solve quantitative problems in a number of areas. Schultz, Emeric. J. Chem. Educ.2008, 85, 386.

A Simplified Model To Predict the Effect of Increasing Atmospheric CO2 on Carbonate Chemistry in the OceanBrian J. Bozlee, Maria Janebo, and Ginger Jahn The chemistry of dissolved inorganic carbon in seawater is reviewed and used to predict the potential effect of rising levels of carbon dioxide in the atmosphere. It is found that calcium carbonate may become unsaturated in cold surface seawater by the year 2100, resulting in the destruction of calcifying organisms such as coral.

Let Us Give Lewis Acid–Base Theory the Priority It DeservesAlan A. Shaffer The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept. Shaffer, Alan A. J. Chem. Educ.2006, 83, 1746.
Chemical & Physical ChangeAmerican Chemical Society Everything you see and touch has the ability to change. Sometimes substances change to form new substances. This is called a chemical change. Other times substances change but keep the same identity. This is called a physical change. Try these activities to learn more about chemical and physical change.

Introduction of Aquatic Chemistry in General Chemistry Curriculum;Spreadsheet Calculation ApproachesChulsung Kim Fundamental aquatic chemistry concepts may be introduced in general chemistry classes by computing ionization fractions and buffer intensity of aqueous phase carbonate systems. This Excel spreadsheet may used to build graphic presentations of a titration curve, distribution diagram, and buffer intensity as a function of pH. Accompanying activities are designed to enhance the concepts of acid-base equilibrium through exploring the relationship between pKa/pKb, pH of the solution, ionization fractions, and buffer intensity, and to exercise students graphing skills.
