Question

Which branch of chemistry deals with the separation, quantitative analysis, qualitative analysis and identification of substances?

  1. Organic chemistry
  2. Inorganic chemistry
  3. Physical chemistry
  4. Analytical chemistry

hintHint:

This field of chemistry requires traditional as well as modern equipment for the purpose of such analysis.

The correct answer is: Analytical chemistry


    • Analytical chemistry is the branch of chemistry that deals with the separation, quantitative analysis, qualitative analysis, and identification of substances. 
    • The process of separation involves the removal of certainly required substances from the mixture. The process of calculating the concentration of an analyte from the mixture is referred to as quantitative analysis. And, the process of identifying the analyte in the mixture is known as qualitative analysis. 
    • The branch of chemistry deals with all these three purposes and is known as analytical chemistry. Thus, it manages the analyses of various types of substances. 

    The traditional methods include flame tests, the Kastle Meyer test, etc. whereas modern methods include spectrophotometry, calorimetry, etc.
