Term
Electrolytes
Definition
Substances dissassociate into ions when dissolved in water to form solutions that conduct electricity.
Term
Nonelectrolytes
Definition
Compounds that do not disassociate into ions when dissolved in water and do not conduct electricity.
Term
Weak electrolytes
Definition
Substances that do not completely ionize when dissolve in water and have a weak electrical conductivity.
Term
Strong electrolytes
Definition
Substances that do completely ionize when dissolved in water and have a strong electrical conductivity.
Term
Strong acid
Definition
Acids that completely ionize when dissolved in water and are good conductors of electricity.
Term
Weak acid
Definition
Acids that do not completely ionize when dissolved in water and are poor conductors of electricity.
Term
What kind of arrows are in the chemical reaction for a weak and a strong acid?
Definition
A one way arrow to the products for strong, a two way arrow for weak.
Term
Soluable
Definition
Dissolves in water
Term
Insoluable
Definition
Does not dissolve in water
Term
Ions that create soluable compounds
Definition
Li, Na, K, NH4, NO3, C2H3O2,
Term
Precipitation Reaction
Definition
Reactions that result in precipitates.
Term
Precipitate
Definition
Solids that form from insolube compounds in the products.
Term
How do ions combine in a chemical reaction?
Definition
Anions pair with cations.
Term
Molecular Equation
Definition
An equation that shows the complete neutral formulas for each compound in the reaction, as if they existed as molecules.
Term
Complete Ionic Equation
Definition
An equation that lists all the ions present in a chemical reaction.
Term
Spectator Ions
Definition
Ions not involved in the formation of a reaction's driving force.
Term
Net Ionic Equation
Definition
Equations that only show part of the reaction which is the driving force.
Term
Acid-base reaction
Definition
A reaction wherein an acid and base react with each other, producing water, and in some cases, a weak electrolyte (salt).
Term
Gas Evolution Reaction
Definition
A reaction where a gas forms, resulting in bubbling.
Term
Arrhenius definition of acids and bases
Definition
Acid: Substance that produces H+ ions in an aqueous solution.
Base: Substance that produces OH- ions in an aqueous solution.
Term
Hydronium Ions
Definition
A water molecule with an extra proton (an H+ ion).
Term
Polyprotic Acids
Definition
Acids that contain more than one ionizable ion, and release the sequentially.
Term
Diprotic Acid
Definition
An polyprotic acid that is strong in its first ionization proton, and weak in its second ionization proton.
Term
Salt
Definition
An ionic compound. (that's it)
A salt is typically produced in an acid-base reaction, in addition to H2O.
