This site offers Java-based applets as organized in 4 categories: analytical and general chemistry, instrumental chemical analysis, instrumentation/signal processing, data analysis/chemometrics. Each applet includes a short introduction followed by a user controlled input of experimental conditions, such as seen for diffusion in electrochemistry.The website is available here .
Analysis of paint helps establish authenticity or works of art. This laboratory experiment, still under development, helps students put measurements in context. The linked discussion forum will allow readers and the author to collaborate in improving the experiment.The website is available here .
This website provides a set of short videos which demonstrate to quantitative analysis students the basic steps and visual changes encountered for the following experiments: Mohr titration (for chloride), acid-base titrations, and gravimetry for iron and nickel. A cursory knowledge of German is needed. However, individuals with some knowledge in these techniques can interpret these videos…
This site, WebElements, is a sourced of information on all the elements of the periodic chart. Clicking "on" an element in the periodic chart brings basic information of the element, like atomic number and weight, and a picture of what the element appears visually. If you go to the "scholar edition" additional information about…
This website contains a JAVA applet that simulates the titration of an unknown acid or base, and provides a graphical output of the titration curve. The unknown compounds are taken from a list of amino acids. Students set up the parameters of the titration, and then create a simulated pH curve. From this they are…
An interactive set of applet-based demonstrations (many modeled as experimental measurements) that illustrate the concepts and calculations of chemical equilibria. The site demonstrates equilibrium processes in a reaction vessel by plotting the concentration of reactants and products over time. The site would be a good supplement for a class in general chemistry or quantitative analysis.

In this paper, the authors have information about a real world situation that can be used as a context to situate the lab and this is the main contribution of the paper. Their collaboration with Delta is an excellent example of using local industry to authenticate the problem. While there are not too…
The paper contains a syllabus of a redesigned quantitative analysis lab. In its new form, the lab is almost entirely instrumental. The description has sufficient detail to assist a fellow instructor to adopt the experiments. A rationale for the experiments and the lab protocols has also been provided.The website is available here .
