    Study Notes

    Analytical Chemistry

    • Analytical chemistry involves the separation, identification, and quantification of matter.
    • It involves the use of classical methods along with modern methods involving the use of scientific instruments.

    Methods Used in Analytical Chemistry

    • The methods used to determine the identity and the quantity of the analytes can be broadly divided into:
      • Classical methods
      • Instrumental methods

    Branches of Analytical Chemistry

    • Two sub-branches come under analytical chemistry:
      • Quantitative Analysis
      • Qualitative Analysis

    Quantitative Analysis

    • Quantitative Analysis is a method of determining the absolute or relative quantity regarding the concentration of one or more substances present in a sample or compound.
    • Examples of Quantitative analysis techniques include:
      • Gravimetric Analysis
      • Volumetric analysis

    Qualitative Analysis

    • Qualitative Analysis deals with the determination of the quality of a particular compound, irrespective of its quantity or concentration.
    • Examples of Qualitative analysis methods include:
      • Chemical tests
      • Flame tests

    Importance of Analytical Chemistry

    • Analytical chemistry is taught in almost all schools and colleges.
