Accelerating methods for shelf life prediction

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.

What are some examples of a suspension?

Whole milk will separate into milk and cream after time. Homogenized milk you can buy will stay together much longer because it has become an emulsion. The peanut oil in peanut butter will separate out unless it is well homogenized.

The difference between mixtures, solutions and suspensions

In chemistry, a solution is a homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.

What are the differences between solutions, suspensions, colloids, and pure substances in chemistry?

A Pure substance is basically made up of either same kind of atom or molecule which has definite and constant composition with distinct chemical properties for instance water. A Solution on the other hand is a mixture of two or more substances where the solute is dissolved in a solvent such as sugar in water.

Atomic mass

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.


A suspension mixture is usually created by stirring together two or more ingredients, where the particles are typically large enough to be seen by the unaided eye or a magnifying glass. The ingredients of a suspension mixture are heterogeneous, meaning that they are not evening distributed throughout. Most mixtures are suspension mixtures.

Bubble Suspension

Bubble solution note: If you have trouble making good bubbles, try using distilled water instead of tap water. Aging the solution for at least a day before use significantly increases the lifetime of the bubbles.

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.
