What is a solution? | A mixture of one substance dissolving into another substance causing a homogeneous effect |
What is a suspension? | A mixture in which particles of a substance do not dissolve but are dispersed throughout a gas or liquid |
What is solubility? | The amount of a solid that dissolves in a solvent |
Increasing temperature increases? | Solubiltiy |

What is a colloid? | A mixture in which very small particles of a substance are evenly distributed throughout another substance |
Paint, milk, fog are examples of? | Colloids |
What is an unsaturated solution? | A solution that has less than the amount of solute that can be dissolved at a particular temperature |
What is a saturated solution? | A solution that has the maximum amount of solute particles that can be dissolved at a particular temperature in the presence of undissolved particles of solute |
What is a supersaturated solution? | A solution that contains a higher amount of solute that it can hold in a given amount of solvent at a particular temperature |
What happens when there is excess solute in a solution? | Crystallization |
