| Term | Definition |
|---|---|
| Electrolyte | solutions that conduct electricity because they disassociate into ions |
| Salts | Ionic bonds -- metal with a non metal |
| Acids | Start with H+ |
| Monoprotic acid | an acid that can donate only one proton |
| Polyprotic acid | an acid that can donate more than one proton |
| Base | Metal with OH- (Hydroxide ion) |
| Non electrolytes | Solutions which do not conduct electricity |
| Salts, Acids, and Bases are all what? | Electrolytes |
| Arrhenius theory | - Acids yield H+, Bases yield OH- - Water is amophoteric (meaning it can act as both an acid and a base) |
| Nuteralization of Acids and Bases | - Acids nuteralize Bases and Bases neutralizes acids - Acid + Base --> Salt H20 + (HOH) - Double replacement reaction |
| Bronsted + Lowery theory | - Expands definition of Acids and Bases - Acid is a molecule or ion that is a proton donor - Base is a molecule or proton that is a proton acceptor - Species with most H+ is acid |
| Conjugate acid base pairs | A related set of acids and bases that differ by one H+ |
| H30+ is called what? | Hydronium ion (acidic) |
| OH- is called what? | Hydroxide ion (Basic) |
| All water solutions must contain _______ | Both Hydronium and Hydroxide ions |
| What must the exponents of H+ and OH- add up to | -14 |
| pH scale | Expresses the acidity or bascity of a solution |
| Acids have _____ pH | Low pH |
| Bases have _____ pH | High pH |
| If H+ is equal to 1 x 10^-8 M, what is the pH? | 8, basic |
