  4. Coulometry - Wikipedia

    en.wikipedia.org/wiki/Coulometry

    In analytical electrochemistry, coulometry is the measure of charge transfer during an electrochemical redox reaction. [1] It can be used for precision measurements of charge, but coulometry is mainly used for analytical applications to determine the amount of matter transformed.

  5. Metal halides - Wikipedia

    en.wikipedia.org/wiki/Metal_halides

    where M is the metal, X is the halogen, and MX n is the metal halide. Sample of silver chloride. In practice, this type of reaction may be very exothermic, hence impractical as a preparative technique. Additionally, many transition metals can adopt multiple oxidation states, which complicates matters. As the halogens are strong oxidizers ...

  6. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.
