Ch. 7 Voacb Flashcards
Precipitation
the process of transforming a dissolved substance into an insoluble solid from a supersaturated solution
Precipitate
The solid that is formed during precipitation
Precipitation reaction
A reaction in which an insoluble substance forms and separates from the solution as a solid
Strong electrolyte
A material that, when dissolved in water, gives a solution that conducts an electric current very efficiently
Soluble solid
A solid that readily dissolves in water
Insoluble solid
A solid where such a tiny amount of it dissolves in water that it is undetectable by the human eye
Slightly soluble
A solid which has a low solubility
Molecular equation
An equation representing a reaction in solution and showing the reactants and products in
undissociated form, whether they are strong or weak electrolytes
Complete ionic equation
An equation that shows as ions all substances that are strong electrolytes
Spectator ions
lons present in solution that do not participate directly in a reaction
Net ionic equation
An equation for a reaction in solution, representing strong electrolytes as ions and showing only those components that are directly involved in the chemical change
Acid
A chemical substance, usually a liquid, which contains hydrogen and can react with other substances to form salts
Strong acid
An acid that completely dissociates (ionizes) to produce H+ ion and the conjugate base
Base
A substance that can neutralize the acid by reacting with hydrogen ions
Strong base
A metal hydroxide compound that completely dissociates into its ions in water
Salt
lonic compounds
Oxidation-reduction reaction
A reaction that involves the transfer of electrons between chemical species.
Precipitation reaction
A reaction in which an insoluble substance forms and separates from the solution as a solid
Double-displacement reaction
A reaction is which the positive and negative ions of two compounds exchange places.
Acid-base reaction
A reaction in which an acid reacts with a base and the two neutralize each other, producing a salt and water.
Combustion reaction
Vigorous and exothermic oxidation-reduction reactions that take place between certain substances (particularly organic compounds) and oxygen
Synthesis (combination) reaction
A reaction in which two or more simple elements or compounds merge together to form a more complex compound.
Decomposition reaction
A reaction in which a compound can be broken down into simpler compounds or all the way to the component elements by heating or by the application of an electric current
