Suspension

Solution
- Suspensions are heterogeneous mixtures. The solute particles in this mixture remain suspended throughout the bulk of the medium.
- The particles can be seen with the naked eye. Suspension shows the Tyndall effect. The solute particles settle down when the mixture is left undisturbed.
- This means that suspensions are unstable. Suspensions can be separated by the method of filtration.
- For example, mixtures of chalk powder and water, wheat flour and water.

A group of students took an old shoebox and covered it with black paper from all sides. They fixed a source of light (a torch) at one end of the box by making a hole in it and making another hole on the other side to view the light. They placed a milk sample contained in a beaker/tumbler in the box as shown in Fig.2.4. They were amazed to see that milk taken in the tumbler was illuminated. They tried the same activity by taking a salt solution but found that light simply passed through it?
