Answer:
Homogeneous mixture refers to a mixture in which the components are uniformly distributed throughout the mixture, and the composition and properties are the same throughout the sample. In other words, the mixture has a uniform appearance and properties, and it is difficult to distinguish the individual components. Examples of homogeneous mixtures include solutions, alloys, and some types of gels.
Heterogeneous mixture refers to a mixture in which the components are not uniformly distributed throughout the mixture, and the composition and properties may vary in different parts of the sample. In other words, the mixture has a non-uniform appearance and properties, and the individual components can be easily distinguished. Examples of heterogeneous mixtures include suspensions, colloids, and emulsions. In a suspension, the solid particles are dispersed in a liquid but they can settle out over time. In a colloid, the solid particles or droplets are dispersed in a liquid and can remain suspended for a longer period of time. In an emulsion, two immiscible liquids are mixed together, and one of the liquids is dispersed in small droplets in the other liquid.
