Frage	Antworten
Acids	Sour, turns red litmus blue, has a pH below 7, neutralize bases, reacts with metals to form hydrogen gas, and ionizes to produce hydronium ions.
Bases	Bitter, turns red litmus blue, has a pH greater than 7, neutralizes acids, feels slippery, dissociates into hydroxide ions.
Arrhenius Definition	Acids dissociate in solution to produce H+ ions and bases dissociate in solution to produce OH- ions. Criticisms include non-metal oxides are acidic, metallic oxides are basic, metal salts are acidic, and lone protons shouldn't exist.
Revised A/B Definition Bronsted-Lowry Definition	Acids ionize to make H3O+ ions and bases dissociate or ionize to make OH- ions. Acids are proton donors and bases are proton acceptors. All reactions include acceptors and donors that form conjugate acid base pairs.
Species that dissociate	Ionic Soluble Compounds All Strong Acids
Species that do not dissociate	All insoluble ionic compounds Weak Acids Molecular Compounds Polyatomic Species
Amphiprotic Species	Species that can be either an acid or a base in a Bronsted-Lowry reaction. The most common one is water.
pH Scale	Goes from 0-14 and can extend beyond. Each pH unit is 1x10^-1 units.
