Acids (Arrhenius Theory) z Acids are substances that dissociate in aqueous solutions to form H + . z Monoprotic acids: z Polyprotic acids: Bases (Arrhenius Theory) Bases are substances that produce hydroxide ions, OH - , when dissolved in water Bronsted – Lowry Theory Acid: (molecules or ions) donates a proton (H + ) to another molecule or ion in a proton-transfer reaction. Base: (molecules or ions) accepts a proton (H + ) in a proton-transfer reaction Weak Acids and Weak Bases only partially ionized in solution. Weak acids:
