Mixtures
- Homogenous mixtures
- 2 or more particles are mixed together so well that you only see one thing
- Composition is uniform throughout
- Composition is spread evenly
- Pure Substance
- Only one kind of particle in it
- Heterogenous materials
- Composition is not spread evenly
- Homogenous Materials
- One set of properties
- No physical separation between particles
- Composition is spread evenly
- Solute: What is dissolved
- Solvent: What dissolves the solute
Solutions
- Solute is equally distributed in solvent
- Saturated solution
- Concentration of solute is at a maximum
- No more solute can dissolve
- Supersaturated Solution
- At a high temperature, solution appears saturated
- At lower temperatures, solute will precipitate out
- There is more solute in the solvent than can be dissolved
- Unsaturated solution
- Concentration of solute is below maximum
- More of the solute can dissolve
