A homogeneous mixture is a combination of two or more substances that is uniform in composition and appearance throughout — you cannot see distinct parts. The components are mixed at the molecular or ionic level so the mixture has the same properties and composition in any sample taken.
Key points
- Uniform composition and appearance throughout (single phase).
- Components retain their own chemical identities (not chemically bonded like in a compound).
- Examples: salt water, air, vinegar, brass (copper + zinc), sugar dissolved in water.
- Common separation methods: distillation, evaporation/crystallization, chromatography.
Contrast
- Heterogeneous mixture: non-uniform, with visibly distinct phases or parts (e.g., salad, sand in water).
- Note: colloids (milk, fog) may look uniform to the eye but have dispersed particles that make them different from true solutions.
