Term
Precipitation
Definition
A chemical reaction where a solid is formed.
Term
Precipitate
Definition
The solid that forms as a result of a chemical reaction.
Term
Precipitation Reaction
Definition
The chemical reaction where a solid is formed.
Term
Strong Electrolyte
Definition
A material that, when dissolved in water, dissociates (ionizes) completely & gives a solution that conducts an electric current very efficiently.
Term
Soluble Solid
Definition
A solid that readily dissolves in water.  The solid "disappears" as the ions are dispersed in the water.
Term
Insoluble (slightly soluble)
Definition
SolidA solid where such a tiny amount dissolves in water that it is undetectable with the naked eye.
Term
Molecular Equation
Definition
An equation representing a reaction in a solution & showing the reactants and products in undissociated form, whether they are strong or weak electrolytes.
Term
Complete Ionic Equation
Definition
An equation that shows as ions all substances that are strong electrolytes.
Term
Spectator Ions
Definition
Ions present in solution that do not participate directly in a reaction.
Term
Net Ionic Equation
Definition
An equation for a reaction in solution; representing strong electrolytes as ions & showing only those components that are directly involved in the chemical change.
Term
Acid
Definition
A substance that produces hydrogen ions in aqueous solution; a proton donor.
Term
Strong Acid
Definition
An acid that completely dissociates (ionizes) to produce H+ ions & the conjugate base.
Term
Base
Definition
A substance that produces hydroxide ions in aqueous solution; a proton acceptor.
Term
Strong Base
Definition
A metal hydroxide compound that completely dissociates into its ions in water.
Term
Salt
Definition
An ionic compound.
Term
Oxidation-Reduction Reaction
Definition
A reaction in which one or more electrons are transferred.
Term
Double-Displacement Reaction
Definition
A chemical reaction where both chemical compounds reverse in the final product of the reaction.
Term
Acid-Base Reaction
Definition
A chemical reaction involving hydrogen ions forming a strong acid & creating liquid water as a product.
Term
Single-Displacement Reaction
Definition
A chemical reaction where only either a single anion or cation is exchanged in the reaction.
Term
Combustion Reaction
Definition
The vigorous & exothermic oxidation-reduction reaction that takes place between certain substances (particularly organic compounds) and oxygen.
Term
Synthesis (Combination) Reaction
Definition
A reaction where a given compound is formed from simpler elements.
Term
Decomposition Reaction
Definition
A reaction where a compound is broken down into simpler compounds of the base elements.
