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.
