Arrhenius acid

a substance that produces H+ (hydrogen ions, protons) or H3O+ (hydronium ions) as the only positive ions in solution
*See Table K

Arrhenius base

a substance that produces OH- (hydroxide ions) as the only negative ions in solution
*See Table L

alternate definition of acid

a proton (H+) DONOR

alternate definition of base

a proton (H+) ACCEPTOR

hydrogen ion

H+ (this is an acid)

hydronium ion

H3O+ (this is an acid)
*Table E

hydroxide ion

OH- (this is a base)
*Table E

electrolyte

a substance that conducts electricity when added to a solution (breaks apart into IONS)
Ex: acids, bases, and salts (ionic compounds)

indicator

a chemical that changes color at different pH values
*Table M

neutralization

a type of reaction in which an acid and a base form water and a salt
acid + base --> water + salt

salt

an ionic compound which is neither an acid or a base
Metal + Nonmetal
(or polyatomic ions)

titration

process in which a solution of known concentration is used to determine the concentration of another solution
*Table T: MaVa = MbVb

pH

a measure of how acidic or basic a solution is
acid = 1-7
base = 7-14
neutral = 7
