Define solute.

A solute is defined as the substance that is dissolved in a solution. When a solute is mixed with a solvent, it forms a homogeneous mixture known as a solution. For example, when salt (the solute) is mixed with water (the solvent), the salt dissolves to create a saline solution. This concept is fundamental in chemistry as it relates to solutions, concentration, and the interactions between different substances in various states. Understanding what a solute is helps clarify the nature of mixtures and how different substances interact at the molecular level.
