Neutralization Reaction A reaction between an acid and a base Spectator ions are ions that do not change during the reaction between H 3 O + and OH-.

Salts Strong acids and bases react to form water and a salt Salts are ionic compounds that form when a metal atom or a positive radical replaces the hydrogen of an acid Salts are often soluble in water

Not all neutralization reactions produce neutral solutions The final pH of a solution depends on the amounts of acid and base that are combined AND whether they are strong or weak

Titration Process of gradually adding one solution to another solution in the presence of an indicator to determine the concentration of one of the solutions During process, the color changes

Equivalence Point Original amount of the acid equals the original amount of the base Can occur at the pH 7 – which is neutral But the equivalence point is not always neutral –Strong base and weak acid –Weak base and strong acid

Salts (including NaCl, but not limited to NaCl) Have many different uses –Seasoning on food –Water softeners –Medical diagnosis Are all around us –In food –Building materials –Soaps –Detergents
