Liquid solutions are homogeneous mixtures where a solute is dissolved in a solvent. The solute can be a solid, liquid, or gas, while the solvent is typically a liquid, most commonly water. When the solute dissolves, it breaks down into smaller particles that are evenly distributed throughout the solvent, resulting in a clear and uniform mixture. These solutions can vary in concentration, which refers to the amount of solute present in a given volume of solvent. Common examples of liquid solutions include saltwater, where salt is the solute and water is the solvent, and sugar water, where sugar is dissolved in water.
