A saturated solution is a solution that contains the maximum amount of solute that can be dissolved in a solvent at a given temperature and pressure. For example, when you add sugar to water, the solution becomes saturated when no more sugar can dissolve, and some sugar remains at the bottom of the container.

A pure substance is a material that has a constant composition and consistent properties throughout the sample. An example of a pure substance is distilled water, which contains only water molecules and no impurities or other substances.

A colloid is a mixture in which fine particles are dispersed throughout a liquid or gas but do not settle out over time. An example of a colloid is milk, where fat globules are dispersed in water, giving it a homogeneous appearance.

A saturated solution is one that holds the maximum amount of solute at a specific temperature and pressure. For instance, when sugar is added to water, the solution reaches saturation when no more sugar can dissolve, leaving some undissolved sugar at the bottom.

Characteristics of Pure Substances

A pure substance has a uniform composition and consistent properties throughout. An example is distilled water, which consists solely of water molecules without any impurities.

Understanding Colloids

A colloid is a mixture where tiny particles are evenly distributed within a liquid or gas and do not settle over time. Milk is a common example, as it contains fat globules suspended in water, resulting in a smooth, uniform appearance.

• Saturated Solution: Maximum solute dissolved.
• Pure Substance: Consistent composition, like distilled water.
• Colloid: Stable mixture, such as milk.
