What Are Suspension?

A solution is a mixture in which its components are evenly mixed. A solution is formed when one or more solutes dissolve in a solvent. This solute is the substance that dissolves. The solvent is the substance that the solute or solutes dissolve in and it forms the bulk of the solution. In a sugar solution, the sugar is the solute and the water in the solvent. The most common type of solutions that we are most familiar with are those in which a solid, a liquid or a gas dissolves in a liquid solvent.

However, there are many solutions which are formed by dissolving a solid in another solid, a gas in another gas or by another combination of the three physical states. The particles are also two big to pass though the filter paper. Hence, they are left behind as residue when a suspension is filtered. The nature of suspension will be investigated experimentally by doing some laboratory tests.

Solid particles remain suspended but settle after prolonged standing appears heterogeneous to the naked eye........
