Question

The particle of a suspension will be of size:
A.) Greater than $100nm$
B.) Between $1nm$ to $100nm$
C.) Less than $1nm$
D.) Less than $0.1nm$

Answer 1

The suspension can be defined as a heterogeneous mixture in which particles of the solute do not dissolve in the solvent but remain suspended throughout the bulk of the solvent and it can be easily seen by naked eyes.

Complete step by step answer:
As we know that heterogeneous mixtures are those mixtures which do not have uniform composition. There are two types of heterogeneous mixtures which are suspension and emulsion. The suspension is defined as a heterogeneous mixture in which the solute particles are spread throughout the liquid without dissolving in it. The particles of suspension are visible with naked eyes and can be seen with the help of a microscope. The particles of suspension scatter a beam of light when it passes through a beam of light and also the path of it is visible. The particles of suspension are sufficiently large for the sedimentation. These particles have diameter which is greater than $100nm$.

Hence, option A.) is the correct answer.

Additional information:
The particles of a suspension can be easily separated by the process of filtration. This is because the particles of suspension do not pass through a filter paper. Some examples of suspension are: mixture of water and mud, mixture of sand particles and water, mixture of flour and water, milk of magnesia, mixture of chalk and water, etc.

Note:
Remember that the particles of suspension settle down after some time. Also, when a beam of light passes through a suspension then the light disperses the light which is due to the large size of the particles of the suspension.
