Question

What are the properties of suspension?

Answer 1

Hint: When any substance is added into a solvent, then a solution is formed. There may be various types of solution that include colloidal solutions, saturated solutions or suspension. The nature of solution depends on the distribution and the dissolution of the solute particles in the solvent. These may result in homogeneous or heterogeneous solutions.

Complete answer:
The substance added in small amounts is the solute, while in which it is added is the solvent, together they both make the components of a solution. A suspension is that type of solution whose particles are suspended and can be seen with the naked eye. The particles are a type of solid solute which may be added into any liquid solvent that may not get dissolved.
The properties of suspension are:
-a suspension is a form of a heterogeneous mixture that contains the solid suspended solute particles throughout the solution as they do not dissolve into the solvent.
-the particles of suspension are mobile and when agitated they get mixed up in the solvent without dissolving, but when the solution stands for a while, then the particles settle at the bottom of the solution.
-the suspended particles can be obtained through filtration of the solution by the filter paper, as the particles do not pass through the filter paper.
- the particles, if they are of small size, then they are able to scatter a beam of light when passed through the solution.
-the suspended molecules in a suspension can be visible through a naked eye.
- some examples of suspension are, sand in water, chalk in water, muddy water etc.
Hence, the properties of a suspension are listed above.

Note:
The heterogeneous mixtures are the mixtures that contain irregular distribution of particles throughout the mixture. While homogenous mixtures have a uniform and regular arrangement of particles. Suspension may not always be a liquid, it can be a gas like aerosol, where solid particles are suspended in air.
