This chapter discusses that everything around us isn't always in its pure form. For instance, wood, pens, milk, and air are all made up of mixtures. Mixtures are combinations of different kinds of pure substances.
There are three main types of mixtures:
1. Solution: A solution is like a smooth blend of two or more substances. In solutions, the tiny particles of the substances (called solutes) mix uniformly throughout. It's like when you stir sugar into water until it disappears.
2. Suspension: A suspension is a bit different. It's a mixture where the particles of the solute are spread throughout, but they don't dissolve. Think of it as sand in water. The sand doesn't disappear; you can still see it.
3. Colloidal Solution: Now, a colloidal solution is something in between. It's a mixture that seems the same all over, even though it's made of tiny particles of solute. These particles are larger than those in a solution but smaller than those in a suspension. So, it's a bit like a mix of both.
