What are the two parts of a solution?

• A. Liquid and gas
• B. Solvent and solute
• C. Soluble and insoluble
• D. Base and acid

Answer: (B)

A solution consists of two main components: the solvent and the solute. The solvent is the substance that does the dissolving, typically present in the greatest amount. It is the medium in which the solute is dissolved. Common examples of solvents include water, alcohol, and various organic solvents. The solute is the substance that is being dissolved, and it is present in a lesser amount compared to the solvent. In a saltwater solution, for instance, water acts as the solvent while salt is the solute.

This understanding of solutions is fundamental in various fields, including chemistry, environmental science, and water treatment, where knowing the interaction between different substances is crucial for effective management and treatment of water systems.
