- Mixtures are made of two or more substances in the same place
- Heterogeneous mixtures have small, undissolved particles that do not separate or settle
- Homogeneous mixtures have particles that are easy to see and separate via filtration
Types of Solutions
- Solvent is the substance in the largest amount in a solution
- Solute is the substance dissolved in the solvent
Solubility
