Solubility

A measurement of how much of a solute can dissolve.

Solute

The substance that is dissolved

Solvent

The substance that does the dissolving. 

Solution

A homogenous mixture (uniform throughout).

Miscible

Substances that are completely able to mix together (ex. food coloring & water).

Immiscible

Substances that will not mix together (ex. oil and water).

Concentrated

Solutions with a large amount of solute particles.

Dilute

Solutions with a small amount of solute particles.

Dilution

Reducing the concentration of a solution by adding more solvent without adding more solute.

Unsaturated

A solution that can dissolve more solute.  

Saturated

A solution containing the maximum amount of solute that can be dissolved. 

Supersaturated

A solution containing more than the maximum amount of solute.

Dissolution

A substance dissolves into ions (water molecules surround the ions).

Electrolytes

Substances that dissolve into ions and conduct electricity.

Strong electrolyte

A substance that dissolves and completely ionizes (good conductor).

Weak electrolyte

A substance that only partially dissolves and ionizes (poor conductor)

Nonelectrolytes

 Substances that do not dissolve into ions (does not conduct electricity)

Molarity (M)

moles of solute/liters of solution.

Density of water

1g / 1mL
