What is the difference between a solute and a solvent?
A solute is the substance that is dissolved, while a solvent is the substance that dissolves the solute.
What is the universal solvent?
Water.
What are pure substances?
Elements and compounds.
What are the two types of mixtures?
- Homogenous (solution)
- Heterogenous (mechanical mixture)
What is a homogenous mixture also known as?

What is a heterogenous mixture also known as?
A mechanical mixture.
What are some methods for separating mixtures?

- Filtration
What is the process of separating solutions?
Evaporation, distillation.
What is concentration?
The amount of solute in a given volume of solution.
What is the formula for concentration?
Concentration = mass of solute / volume of solution.
What is solubility?
The ability of a substance to dissolve in a solvent.
What is the formula for solubility?
Solubility = mass of solute / volume of solvent.
Define saturation.
- Unsaturated
- Saturated
- Supersaturated
What affects the dissolve rate?
