Chapter 8: Aqueous Reactions and Solution Stoichiometry

Flashcards covering key terms and concepts in aqueous reactions and solution stoichiometry.

Aqueous solution

A solution that contains water.

Electrolyte

A substance whose aqueous solution allows passage of electricity due to the presence of ions.

Strong electrolyte

Ionic compounds that dissociate completely in aqueous solution.

Weak electrolyte

Compounds that produce limited amounts of ions in solution and remain largely as molecules.

Precipitation reaction

A reaction that produces a solid or precipitate from soluble reactants.

Solubility guidelines

Rules to determine whether ionic compounds are soluble or insoluble in water.

Net ionic equation

An equation that shows only the species that participate in a reaction, excluding spectator ions.

Acid-base reaction

A chemical reaction involving the transfer of protons (H+) between species.

Strong acid

An acid that dissociates completely in solution, producing H+ ions.

Weak acid

An acid that only partially dissociates in solution.

Molarity (M)

The number of moles of solute per liter of solution.

Dilution

The process of preparing a less concentrated solution from a more concentrated one by adding solvent.

Activity series

An arrangement of metals in order of decreasing reactivity.

Stoichiometry

The calculation of reactants and products in chemical reactions.

Chemical indicator

A substance used to determine the endpoint of a titration.

Endpoint of titration

The point at which the titration is completed, indicated by a change in color.

Reducing agent

The species that donates electrons in a redox reaction and is oxidized.

Oxidizing agent

The species that accepts electrons in a redox reaction and is reduced.

Redox reaction

A chemical reaction involving the transfer of electrons between species.
