Key Concepts

Homogeneous Mixtures

Homogeneous mixtures are uniform in composition and appearance, meaning that the individual components are not distinguishable. An example is saltwater, where the salt is completely dissolved, creating a consistent solution. In these mixtures, any sample taken will have the same composition as any other sample.

Heterogeneous Mixtures

Heterogeneous mixtures consist of visibly different substances or phases. The components can often be separated by physical means, and their proportions can vary throughout the mixture. An example is a salad, where you can see and identify the individual ingredients, making it clear that the mixture is not uniform.

Colloids and Suspensions

Colloids and suspensions are specific types of heterogeneous mixtures. In colloids, particles are dispersed throughout but do not settle out, like milk. Suspensions, on the other hand, contain larger particles that can settle over time, such as muddy water. Understanding these distinctions helps classify mixtures accurately.
