Questions and Answers

What is a suspension in chemistry?

  • A mixture where the solid particles dissolve in the fluid
  • A homogeneous mixture of a fluid and solid particles
  • A heterogeneous mixture of a fluid and solid particles (correct)
  • A mixture where the solid particles are smaller and do not settle

    • How are the solid particles dispersed in a suspension?

  • They form a homogeneous mixture with the solvent
  • They settle at the bottom of the container
  • They dissolve in the fluid
  • They are visible under a microscope and float freely in the medium (correct)

    • What distinguishes a suspension from a colloid?

  • The density of the particles
  • The size of the particles and their settling behavior (correct)
  • The particles' ability to dissolve in the fluid
  • The color of the particles

    Study Notes

    Suspensions in Chemistry

    • A suspension is a heterogeneous mixture in which solid particles remain suspended throughout the solvent.
    • In a suspension, the solid particles are dispersed, but not dissolved, in the solvent.
    • The particles in a suspension are typically larger than those in a solution, and are visible to the naked eye or with a microscope.

    Comparison to Colloids

    • A suspension is distinguished from a colloid by the size of the particles: suspensions have larger particles, while colloids have smaller particles that are still larger than those in a solution.
    • A colloid is a type of mixture that is intermediate between a suspension and a solution.

    Comparison to Solutions

    • A suspension is distinguished from a solution by the fact that the particles are not dissolved in the solvent.
    • In a solution, the solute and solvent exist as a homogeneously mixed substance.

    Aerosols

    • A suspension of liquid droplets or fine solid particles in a gas is called an aerosol.
    • An aerosol is a type of mixture that is formed when fine solid particles or liquid droplets are suspended in a gas.

    Atmosphere

    • A suspension is distinguished from particulates in the atmosphere, which are typically smaller and more dispersed.
    • Particulates in the atmosphere can be suspended in the air, but are not necessarily a suspension in the classical sense.
