Types of Mixtures
Mixtures form when two or more substances combine without a chemical reaction. Based on particle size, they are classified as solutions, colloids, or suspensions, which affects how they mix and separate.
Solutions have the tiniest particles, too small to be seen even with a microscope. These particles dissolve completely, forming a uniform, homogeneous mixture. For example, when salt is mixed with water, it dissolves, creating a solution.
Colloids have larger particles than solutions but are too small to settle. They appear uniform but scatter light, creating the Tyndall effect, where light spreads as it passes through a substance.
For instance, milk is a colloid because tiny fat and protein particles stay mixed, giving it a smooth appearance.
Suspensions have the largest particles, which do not dissolve and settle over time if left undisturbed. These are heterogeneous mixtures where components remain separate.
For example, in salad dressing, oil, vinegar, and spices separate when left sitting, showing it is a suspension.
Next time you apply lotion or shake a juice bottle, think about the type of mixture you are using.
