What is Suspension in Science? – Definition, Types & Examples

If you have had the opportunity to go to the beach, you have probably felt grainy sand between your toes while in the water. If you take a scoop of sandy water, place it in a bottle, and try to shake it, what do you suppose will happen? Rather than dissolving in the water, the sand will float around and eventually settle to the bottom. This interaction between sand and water perfectly explains what a suspension is.

In chemistry, what is the meaning of suspension?

If an insoluble substance like barium sulphate or clay is added to water,the particles are large enough to be visible,if not to a naked eye,at least under a microscope. They settle down on standing for some time. Such mixtures are called suspensions.

Word Origin and History for suspension

A suspension, simply put, is a mixture of two substances – one dispersed into the other. Examples of suspensions include droplets of oil in air, and sand in water. Particles in a suspension are easy to see, as they are larger than the particles making up the solution. Because of this quality, these larger particles within a suspension will settle if allowed to stand undisturbed. This inherent quality also makes suspensions very easy to separate through filtration.

References

Suspension is the heterogeneous mixture of two or more substances. In suspension, particles are suspended throughout in bulk and can be seen by naked eyes. In suspensions, particles of solute do not dissolve rather are suspended. Particles of suspension are large enough to scatter rays of light and path of ray is visible through a suspension.

Difference Between Suspension and Solution

Chemistry is the physical science which deals with matter and the changes that it goes through during chemical reactions. It deals with the chemical reaction between substances that are mixed together and how they are transformed into another substance.

Methods for Separating Mixtures

90% of the time, speakers of English use just 7,500 words in speech and writing. These words appear in red, and are graded with stars. One-star words are frequent, two-star words are more frequent, and three-star words are the most frequent.

Definition of Suspension (chemistry)

A colloid may consist of particles suspended in a gas, liquid or solid, although many colloidal properties are most pronounced in liquid colloids. Gas colloids consist of particles suspended in the air or a gas medium, and include fog, smoke and atmospheric dust. Liquid colloids can consist of liquid or solid particles suspended in a liquid medium, such as milk, or incorporate gas bubbles, such as whipped cream. Solid colloids include solid foams, such as plaster, liquid-bearing solids, such as butter or cheese, and firm substances, such as paper.

Suspension in a Sentence

A suspension is a mixture of two non-miscible phases, with one phase dispersed into the other. By definition it is heterogeneous. An example of a homogeneous mixture would be a solution (e.g. salt in water).
