Solution
To make tea, we will use the following steps:
- Take 100 mL of water, which will serve as the solvent.
- Boil water on a gas stove.
- Add one teaspoon of sugar, which acts as a solute.
- Sugar is soluble in water, therefore it dissolves in water and forms a solution.
- Now add roughly half a teaspoon of tea leaves that are insoluble in water.
- Boil the contents for 4 to 5 minutes, then add a half cup of milk and continue to boil for 2-3 minutes.
- Filter the tea using a sieve.
- Tea leaves will be left as residue, and tea will be extracted as filtrate.

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?
