Mixtures, Solutions, Suspensions and Colloids
MIXTURES, SOLUTIONS, SUSPENSIONS AND COLLOIDS
MIXTURES
A mixture is a combination made up of two or more different substances which are mixed but are not chemically bonded. There are also types of mixtures such as homogeneous mixtures and heterogeneous mixtures.
SOLUTIONS
A solution is defined as a homogeneous mixture composed of a solute; a substance dissolved into another substance known as a solvent. They can also be defined as groups of molecules that are mixed up completely in even distribution all around the mixture.
SUSPENSIONS
This is defined as a heterogeneous fluid whose particles are in larger quantity for the fluid it is supposed to be dissolved into. Unlike what is soon going to be defined, colloids, suspensions’ particles eventually settle over time if left undisturbed.
COLLOIDS
This is defined as a substance dispersed evenly throughout another substance. A colloid consists of two phases in its entire substantial form which are a dispersed phase of the solution and a continuous phase.
A colloidal system may be solid, liquid or gaseous in form. Some colloids are translucent which causes particles to be scattered throughout the colloid, whilst other colloids may be opaque or have a slight color.
