ChemistryChapter 17: Separation Techniques
Mixture Types
A homogeneous mixture (a solution, such as brine) cannot be sorted by eye.
Learning objectives
- Define and explain mixture types.
- Apply mixture types to a focused FBISE question.
- Check the answer for correct terms, evidence, working, and units.
Definition
A homogeneous mixture (a solution, such as brine) cannot be sorted by eye. A heterogeneous mixture (sand in water) shows separate parts. The method you pick depends on whether the bits are dissolved or only mixed.

WHAT — MIXTURE TYPES
A homogeneous mixture (a solution, such as brine) cannot be sorted by eye. A heterogeneous mixture (sand in water) shows separate parts. The method you pick depends on whether the bits are dissolved or only mixed.
HOW — Use the idea
Identify what is given, select this topic's rule or evidence, apply it one step at a time, and check the result.
In simple words
Do not merge mixture types with a neighbouring idea that uses a different definition, rule, or method.
