The answer is C. Solution Here's why: Solutions are mixtures that are present everywhere in our daily lives. • Solute: The substance that dissolves in a solvent. For example, sugar is a solute in a sugar-water solution. • Solvent: The substance that dissolves the solute. For example, water is the solvent in a sugar-water solution. • Solutions: The uniform mixture formed when a solute dissolves in a solvent. For example, sugar water is a solution. • Concentration: The amount of solute dissolved in a given amount of solvent. For example, a concentrated sugar solution has a lot of sugar dissolved in it, while a dilute solution has less sugar. Examples of Solutions in Everyday Life: • Saltwater: Salt (solute) dissolves in water (solvent) to form a saltwater solution. • Sugar: Sweetened beverages: Sugar (solute) dissolves in water (solvent) to make a sugary drink. • Air: Oxygen, nitrogen, and other gases (solutes) are dissolved in the air (solvent). • Cleaning solutions: Detergents, soaps, and other cleaning agents (solutes) are dissolved in water (solvent). • Medicines: Many medicines are solutions where active ingredients (solutes) are dissolved in water or other solvents.
