A solution is a homogeneous mixture of solute and solvent. Solutes dissolve in solvents without settling, forming a single-phase system. Solvents determine the solution’s state and aid dispersion. Solubility depends on factors like temperature, pressure, and polarity. Types of solutions and solvents vary by state and composition. Examples include saltwater, soda, alloys, and perfumes.

Matter around us is mostly mixtures, not pure substances. Mixtures can be homogeneous or heterogeneous. Solutions, suspensions, and colloids differ in properties. Pure substances include elements and compounds, with fixed composition and characteristics. Physical and chemical changes alter matter differently. Separation methods help isolate components in mixtures, highlighting the difference between mixtures and pure substances.

Homogeneous and heterogeneous mixtures differ in composition and uniformity. A homogeneous mixture has a uniform appearance with no visible separation, like saltwater or air. In contrast, a heterogeneous mixture consists of distinguishable components, such as sand in water or salad. Learn key differences, characteristics, and examples in this easy-to-understand guide.
