Overview
In this chapter, we learn about how different substances interact with liquids, especially water. Some solids dissolve in water, while others do not. We also explore methods to separate mixtures, which is very useful in daily life and science. Understanding these processes helps us get clean water,
Key Concepts
A substance that dissolves in
A substance that dissolves in a liquid is called soluble, like sugar or salt in water. A substance that does not dissolve is called insoluble, like sa
The substance that dissolves is
The substance that dissolves is the solute (like sugar). The liquid it dissolves in is the solvent (like water). The mixture formed is called a soluti
When two liquids mix completely
When two liquids mix completely, like water and rose syrup, they are miscible. When they do not mix, like oil and water, they are immiscible.
We use different methods to separate
We use different methods to separate mixtures: evaporation and distillation for soluble solids, and sedimentation, decantation, and filtration for ins
