Abstract
This article describes assignments related to the solubility of inorganic salts that can be given in an introductory general chemistry course. Le Châtelier's principle, solubility, unit conversion, and thermodynamics are tied together to calculate heats of solution by two methods: heats of formation and an application of the van't Hoff equation. These assignments address the need for math, graphing, and computer skills in the chemical technology program by developing skill in the use of Microsoft Excel to prepare spreadsheets and graphs and to perform linear and nonlinear curve-fitting. Background information on the value of understanding and predicting solubility is provided.

“Gone” into Solution: Assessing the Effect of Hands-On Activity on Students’ Comprehension of Solubility
Laura B. Bruck and Aaron D. Bruck, Amy J. PhelpsJournal of Chemical Education2010 87 (1), 107-112“Gone” into Solution: Assessing the Effect of Hands-On Activity on Students’ Comprehension of Solubility
Laura B. Bruck and Aaron D. Bruck, Amy J. PhelpsJournal of Chemical Education2010 87 (1), 107-112Solubility is challenging for many general chemistry students, and the interactions of aqueous species are difficult to conceptualize. Derived from the pedagogies of Johnstone, Bloom, and Piaget, our primary research questions probe whether students’ ...
Design of an Excel Spreadsheet To Estimate Rate Constants, Determine Associated Errors, and Choose Curve's Extent
Ruben Elvas-Leitão , Luís Moreira and Filomena MartinsJournal of Chemical Education2006 83 (12), 1879Design of an Excel Spreadsheet To Estimate Rate Constants, Determine Associated Errors, and Choose Curve's Extent
Ruben Elvas-Leitão , Luís Moreira and Filomena MartinsJournal of Chemical Education2006 83 (12), 1879In this article we wish to present a new Microsoft Excel spreadsheet design that enables a prompt calculation of rate constant values (k) and associated errors and also addresses less common features such as the choice of experimental curve's extent. The ...
An Aquatic Chemistry Spreadsheet for General Chemistry Classes
Chulsung KimJournal of Chemical Education2003 80 (11), 1351An Aquatic Chemistry Spreadsheet for General Chemistry Classes
Chulsung KimJournal of Chemical Education2003 80 (11), 1351The Aquatic Chemistry Spreadsheet was produced to help students work through the activities of producing a graph of a titration curve, a distribution diagram, and buffer intensity as a function of pH. These activities help students better understand acid–...
