Branch of chemistry that deals with e complete qualitative and quantitaive analysis of a substance
Correct answer: B. Analytical chemistry
- A. Stoichio chemistry
- B. Analytical chemistry
- C. Physical chemistry
- D. quantum chemistrY
Explanation
The correct option is:(c) Analytical chemistry.Explanation:Analytical chemistry focuses on the qualitative and quantitative analysis of substances. It involves methods and techniques to identify the components present in a sample (qualitative analysis) and determine their concentrations or amounts (quantitative analysis). This field employs various tools and methodologies like spectroscopy, chromatography, titration, and other analytical techniques to assess and quantify substances accurately.Now, let's explore why the other options are incorrect:(a) Stoichiometry:

About Experimental Techniques in Chemistry
Separation methods are selected according to differences in solubility, particle size, volatility and sublimation behaviour. Filtration and crystallisation separate insoluble or dissolved solids, sublimation isolates suitable volatile solids, distillation separates liquids by boiling point, and solvent extraction transfers a substance between immiscible solvents.
