Questions and Answers

What are homogenous mixtures?

  • Can be a suspension or colloid
  • Are made up of two or more substances that spread out uniformly (correct)

    Study Notes

    Homogenous Mixtures

    • Composed of two or more substances uniformly distributed throughout.
    • Example: Saltwater where salt dissolves evenly in water.

    Heterogeneous Mixtures

    • Contain different substances that remain distinct from one another.
    • Always exhibit more than one phase, meaning different parts can be identified easily.
    • Can exist as suspensions or colloids, depending on the particle size and behavior in a medium.

    Suspensions

    • A type of heterogeneous mixture with solid particles that may remain momentarily suspended in a liquid.
    • Requires mechanical agitation (e.g., shaking) to maintain particle dispersion.

    Colloids

    • Mixtures appearing homogeneous but are technically heterogeneous due to the size of their particles.
    • Exhibit properties of both solutions and suspensions yet remain visually uniform.

    Solutions

    • Defined as homogeneous mixtures with two or more components that are evenly distributed.
    • Consist of a solute (the substance being dissolved) and a solvent (the substance doing the dissolving).
    • Can be categorized into three types: gaseous, liquid, and solid solutions, based on their state.
