Definition of Suspensions

Posted: 16 Nov 2011 04:05 PM PST

A suspension is a heterogenous mixture relatively large particles in a medium.

In this type of mixture, the particles eventually settle out of the medium because of their large size or insolubility in the medium. Suspension may appear to be colloidal in nature, but because of the size of the suspended particles, setting (also called precipitation) will eventually occur. After precipitation of the suspended particles, the suspension will cease to exist, instead two distinct layer appear, the clear medium and the precipitated particles.

What is Dillution

Although solutions are more easily, accurately, precisely prepared at higher concentrations, scientist generally work in smaller concentration in the laboratory.

To prepare solutions for laboratory work, scientist must dilute high concentration solutions to low concentration solutions. When diluting solutions from a given concentration to a lower concentration, scientist follow this simple formula:

C1V1 = C2V2

  • C1 and V1 ­are the initial concentration and volume
  • C2 and V2 ­are the final concentration and volume

This simple formula may be used as long as all of the concentration and volume units involved in the calculation are the same. The concentration of an extremely dilute solution may be expressed in several ways, such as part per billion (ppb) or milligrams per deciliter (mg/dl). For the complete list of commonly used units, see the common concentration unit for dilute solutions below:
