Question

Are all solutions mixtures? And are all mixtures solutions?

Answer 1

Hint: Atoms are tiny particles and combine to form molecules. Molecules combine to form mixtures. Thus, the mixture consists of two or more compounds. Solution is a homogeneous mixture of solute and solvent. The solute distributes uniformly in the solvent to form a solution. Thus, all solutions are mixtures but all mixtures are not solutions.

Complete answer:
Molecules are the combination of atoms. Where atoms are tiny particles and combine to form molecules. For example, nitrogen and nitrogen react to form a molecule called dinitrogen which is a gas. Now this nitrogen molecule may react with another molecule to form a mixture.
Mixture is the combination of two or more molecules. Each molecule or compound retains their identity in the mixture.
Some of the examples of mixtures are mixtures of hydrogen gas, nitrogen gas and carbon dioxide.
Solution is a homogeneous mixture of solute and solvent. In which the solute dissolves in the solvent uniformly. Solute is a substance present in less quantity and solvent will be present in high quantity.
As the solution itself consists of solute and solvent which means the two compounds which can also be called as mixture. Thus, all solutions are mixtures whereas all mixtures are not solutions.

Note:
The two or more compounds reacted may not be present in uniform quantities in the mixture. But in case of solution the solute uniformly distributes in the solvent. One should not confuse the mixture and solution although both consist of two compounds sometimes as mixture can be visible by a naked eye whereas solution cannot.
