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…

Students explore titrations of weak acids and based using a titration simulator.

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…

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
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…

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…

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…

Students will learn to:
Predict elution order of compounds
Calculate retention factor and selectivity factor
Explain the effect of mobile phase composition on resolution and peak shape at a molecular level
Use elution gradients to improve separation of compounds in…

Introduction
This Shiny app simulates cyclic voltammetry experiments using the computational method outlined in Gosser, D. K.
