Chemical analysis

    AQA
    GCSE

    Chemical analysis encompasses the set of techniques used to identify and quantify substances within a sample. It begins with distinguishing between pure substances and mixtures using melting and boiling point data, alongside the concept of formulations. The topic extends to separation techniques like chromatography for identifying components of a mixture, and specific qualitative tests for gases, cations, and anions to deduce chemical composition.
