In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not settled out.
Examples of Suspension
Muddy water.
Milk of magnesia.
Sand particles suspended in water.
Flour in water.
Slaked lime for whitewashing.
Paints in which dyes are suspended in turpentine oil.:
what is suspension:
A suspension is a heterogeneous mixture in which the solute particles do not dissolve but remain suspended throughout the bulk of the medium. In other words, suspensions are non – homogeneous systems in which solids are dispersed in liquids. Constituent particles of a suspension are large enough that gravity can pull them down out of the dispersion medium. These particles can be easily separated by the filtration method from the dispersion medium. The size of particles in suspension is at least 100 times larger than particles of solution.
Examples

You can see many examples of solutions in your daily life. A few examples of solutions are listed below –
Mixture of sugar and water.
Tincture of iodine (solution of iodine in alcohol)
Soda water
Air (a homogeneous solution of various gasses)
Alloys (Mixture of two or more metals or a metal and a non – metal which cannot be separated by physical methods. For example – Brass, Stainless steel etc.)
