acids and bases vocab

conjugate acid	the particle formed when a base gains a hydrogen ion ex. NH3 gains a hydrogen ion and becomes NH4 +
acid-base indicator	a substance that undergoes a color change as the concentration of acids or bases changes in a solution.
base	a compound that produces hydroxide ions in solution is a hydrogen-ion acceptor.
salt	an ionic compound.  Acid-base reactions will always result in one of these and water.
titration	method used to determine the concentration of a solution; a solution of known concentration is added to a measured amount of the solution of unknown concentration until an indicator signals the end point.
neutralization reaction	a reaction in which an acid and a base react in an aqueous solution to produce a salt and water.
pH	a number used to denote the hydrogen-ion concentration or acidity  of a solution.  It is the negative log of the hydrogen-ion concentration.
product	a substance formed in a chemical reaction.
ion	an atom or group of atoms that has a positive or negative change; cations are ions with a positive charge, and anions are ions with a negative charge
acid	a compound that produces hydrogen ions in solution, is a hydrogen ion donor
reactant	a starting substance in a chemical equation.
