AP Chem Unit #4

Water

A polar molecule that acts as a common solvent due to its ability to dissolve many substances.

Polarity

Unequal distribution of charge within a molecule that facilitates the ability to dissolve compounds.

Hydration

The process by which water molecules attach to ions, stabilizing them in solution.

Solubility

The ability of a substance to dissolve in a solvent, primarily affected by the attraction among ions and between ions and water.

Electrolyte

A solute that dissolves in water to produce a solution that can conduct electricity.

Strong Acid

An acid that completely dissociates into its ions in solution.

Molarity (M)

A measure of concentration expressed as moles of solute per liter of solution.

Titration

A technique used to determine the concentration of an unknown solution by adding a solution of known concentration.

Oxidation

The process of losing electrons, leading to an increase in oxidation state.

Reduction

The process of gaining electrons, resulting in a decrease in oxidation state.
