Consider the following statements about mixture :
- 1A substance can be separated into other kinds of matter by any physical process.
- 2Dissolved sodium chloride can be separated from water by the physical process of evaporation.
Which of the statements given above is/are correct?
General KnowledgeChemistry
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Both statements capture the defining property of mixtures: unlike compounds, a mixture can be separated into its components by physical processes, and dissolved sodium chloride is recovered from water by the physical process of evaporation. The statements are textbook illustrations (NCERT Class 9) of why mixtures are not pure substances. Hence both are correct.
