1. Acid/ Base properties 2. Arrhenius Theory o Acids contain hydrogen and produce H + o Bases contain hydroxyl and produce OH - o Neutralization is a combination of H + and OH - to produce H 2 O 3. Hydronium Ion o Hydrated hydrogen ion is the species that gives aqueous solutions of acids their characteristic acidic properties 4. Bronsted-Lowery Theory o Acid is a proton donor (H+) o Base is a proton acceptor (OH-) o The stronger the acid the weaker the conjugate base and vice versa 5. Autoionization of water (self-ionization) o Amphiportic = molecule can both donate and accept 6. Amphoterism o ability of a substance to react either as a base or an acid o Example: insoluble metal hydroxides) 7. Strength of acid o Binary acids Ease of ionization depends on Ease of breaking H-X Stability of resulting ion in the solution Bond strength Hydrogen halides become weaker down the period Acid strength is opposite of bond strength Hydronium ion is the strongest acid in aqueous solution
