Lecture 16: Solubility and Solubility Rules

A set of vocabulary flashcards covering key terms related to solubility, electrolytes, and reactions in aqueous solutions.

Dissociation

The process by which ions separate.

Electrolytes

Substances that dissolve in water to produce conducting solutions of ions.

Nonelectrolytes

Substances that do not produce ions in aqueous solutions.

Strong Electrolytes

Compounds that dissociate to a large extent into ions when dissolved in water.

Weak Electrolytes

Compounds that dissociate to a small extent into ions when dissolved in water.

Acids

Molecular compounds that form ions when dissolved in water.

Solubility Rules

Rules used to predict a compound's solubility in water.

Precipitation

Soluble reactants yield an insoluble solid product that falls out of solution.

Precipitate

An insoluble solid that forms from a reaction.

Molecular equation

All substances in the chemical equation are written using their complete formulas.

Complete ionic equation

All of the strong electrolytes are written as ions.

Net ionic equation

Only the ions undergoing change are shown, eliminating spectator ions.

Spectator ion

An ion that appears on both sides of the reaction arrow and is unchanged by the reaction.

Soluble

A compound that dissolves in water.

Insoluble

A compound that does not dissolve in water.
