acidic solution
Contains more hydrogen ions than hydroxide ions
Basic solution
Contains more hydroxide ions than hydrogen ions
Neutral solution
A solution in which the hydronium ion concentration is equal to the hydroxide ion concentration.
Strong Acid
an acid that ionizes completely in aqueous solution
Weak base
a base that reacts with water to form the hydroxide ion and the conjugate acid of the base
Strong base
A base that dissociates completely into ions in solution.
weak acid
an acid that is only slightly ionized in aqueous solution
molarity
the number of moles of solute in one liter of solution
PH
a value that indicated the acidity or alkalinity of a solution on a scale of 0-14, based on the proportion of H+ ions.
POH
The negative of the common logarithm of the hydroxide ion concentration of a solution.
Acid Base indicator
a chemical dye whose color is affected by acidic and basic solutions
Neutralization reaction
the reaction of an acid and a base to form a neutral solution of water and a salt
buffer
an ionic compound that resists changes in its pH
antacid
