Answer 2

Option(c): 'Solution' is not the pure form of matter.

• A substance is said to be in pure form if it is made up of only one type of molecule or particle.
• Pure substances generally cannot be separated by simple physical methods.
• They are classified as elements and compounds.
• An element consists of only one kind of particle which can be atoms or molecules. Example sulfur.
• A compound is a substance that is formed by two or more different types of elements that are united chemically in fixed proportions. For Example, Water is a compound made of molecules.
• Compounds are pure substances. They are made of molecules that consist of the union of atoms of different elements through chemical bonding.
• The structure and properties stay uniform throughout the compound. Therefore compounds can be called Pure Substances.
• A solution is a homogeneous mixture of two or more substances. A solution is formed of a solute and a solvent. The solute is the particular substance that dissolves in the solvent. Example Sugar in water.

Hence, Option(c): 'Solution' is not the pure form of matter.
