Acid Base Titration

Designing an Acid–Base Titration

19. Simulations, a. Acid-base titrations, In Class Activities
Introduction This learning module introduces students to acid-base titrimetry at a level suitable for an introductory course in analytical chemistry. The module assumes students are comfortable with stoichiometric calculations, particularly as they apply to acid-base reactions, that they are familiar with the general shape of a titration curve, and that they appreciate the difference between a…

Acid-Base Titration Simulation

19. Simulations, a. Acid-base titrations
Students will learn to: List and describe the factors/parameters that affect the shape of acid-base titration curves Predict and explain why the change occurs when each of these factors/parameters is adjusted Calculate the pH of solution and articulate its correlation to any point on…

Beer’s Law

19. Simulations, b. Beer's Law, In Class Activities
Introduction This on-line learning module introduces students to Beer’s law with particular attention to the relationships between absorbance, transmittance, and power, and to the fundamental, instrumental, and chemical limitations inherent in the application of Beer’s law. The learning module consists of seven investigations: Investigation 1: Recalling Beer’s Law Investigation 2: Absorbance Spectra Investigation 3: Calibration Curves…

Introduction to Chromatography

19. Simulations, a. Basic chromatographic concepts, c. Peak broadening, d. Fundamental resolution equation, In Class Activities
Introduction This learning module provides an interactive introduction to chromatography with an emphasis on understanding basic chromatographic terms and measurements, and on understanding the factors that affect the quality of a separation. The treatment is independent of the form of chromatography and, although data from GC and HPLC experiments are used to illustrate topics presented in…

GC Elution Order

19. Simulations, b. GC Retention Order
Students will learn to: Predict and explain the elution order of analytes. Explain the effects of temperature programs and flow rate on resolution at the macroscopic and molecular level. Explain the effects of flow rate. Select separation conditions for a…

Chromatography: Use of an HPLC Simulator

19. Simulations, a. General Coverage of HPLC, b. HPLC Retention Order, c. Use of a Simulator, In Class Activities
A series of collaborative learning activities using the free HPLC Simulator (http://www.multidlc.org/hplcsim) developed by Thomas J. Lauer and Dwight R. Stoll of Gustavus Adolphus University. The Chromatography Basics activities introduce the parameters tR, tM, k, resolution, peak width, N, H, Purnell equation for resolution, van Deemter curve, linear velocity, optimum linear velocity, and optional discussion…
