This site offers an introductory course (as a MOOC) on the estimation of measurement uncertainty specifically related to chemical analysis (analytical chemistry). The course gives the main concepts and mathematical apparatus of measurement uncertainty estimation and introduces two principal approaches to measurement uncertainty estimation – the ISO GUM modeling approach (aa “bottom-up” approach) and the single-lab…
A complete textbook for Quantitative Analysis is freely downloadable. Teach yourself Analytical Chemistry, or be part of a class on the subject.

This online article describes an inquiry-based experience designed to integrate concepts in water quality and geology for pre-education science students preparing to become teachers at the primary and secondary level. The field and laboratory exercise could be used to effectively introduce equilibrium chemistry in an introductory or environmental chemistry course, and courses for non-majors.The website is…
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 .
This paper titled, Flow Injection Analysis in the Undergraduate Laboratory, by Rocha and Nobrega was published in the Chemical Educator. It describes two basic experiments. One is the measurement of copper using PAR reagent as carrier in a single line FIA system. Increasing the reaction coil length results in double peaks. Refractive index effects are demonstrated…
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 USGS method explains the use of fluxes for preparation of coal for elemental analysis. Useful to supplement textbooks concerning sample preparation and may be useful in designing an XRF laboratory experiment.The website is available here .
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.

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 .
