Answer 2

Purity of the sample can be assessed by physical and chemical methods

Explanation:

• Physical comparison is the best method to check the purity of the sample. It can detect impurities like dirt or colored components.

• The colorimetric method is another widely used strategy of determining the purity of a chemical compound. Biochemically, some chemical compounds change into a particular color when they are exposed to a certain chemical. Colorimetry is the method used to check the sample purity.
• Comparison of boiling and melting points . Pure chemicals have fixed boiling and melting points. Impurities lead to a change , increase or decrease of boiling or melting point.
