Study Notes
Homogeneous Mixture vs Heterogeneous Mixture
- A homogeneous mixture has visibly indistinguishable parts, appearing as one clear solution.
- A homogeneous mixture has uniform composition, meaning the composition is the same everywhere in the mixture.
Examples of Homogeneous Mixtures
- Saltwater: appears as one clear solution, with no visible distinction between salt and water.
- Brass: an alloy of zinc and copper, with atoms distributed uniformly throughout the material.
- Air: a mixture of nitrogen, oxygen, argon, water vapor, and carbon dioxide, with a uniform composition.
Heterogeneous Mixture
- A heterogeneous mixture has multiple distinguishable parts.
- The composition of a heterogeneous mixture can vary by position.
Examples of Heterogeneous Mixtures
- Oil and Water: do not mix, with visible distinct layers of oil and water.
- Sand and Water: sand does not dissolve in water, resulting in visible distinguishable parts.
- Tossed Salad with Ranch: a mixture with visible, distinguishable parts of salad and ranch.
Key Points to Identify Type of Mixture
- If you can see only one clear solution, it's a homogeneous mixture.
- If you can see multiple distinguishable parts, it's a heterogeneous mixture.

Identifying Types of Mixtures
- One clear solution = homogeneous mixture.
- Multiple distinguishable parts = heterogeneous mixture.
