|---|---|
 Bronsted-Lowry Acid | A substance capable of donating a proton |
| Bronsted-Lowary Base | A substance capable of accepting a proyon |
| Lewis Acid | A substance that can accept a pair of electrons |
| Lewis Base | A substance that can donate a pair of electrons |
| Acids in aqueous solution | .form solutions with ph less than 7 .react with active metals to give a salt and hydrogen gas .react with bases, such as metal oxides to form salt and water |
| Bases in aqueous solution | ph greater than 7 react with acids to form salts |
| Conjugate acid-base pairs | differ by one proton |
| dative bond | Lewis acids result in covalent bonds |
| note | all bronsted-lowry acids are lewis acids |
| Strong Acids | equilibrium lies to the right, it means that the acid hs dissociated fully |
| Weak Acid | equilibrium lies to left, it means that the acid has dissociated only partially |
| HCl | Hydrochloric acid strong acid |
| HNO3 | Nitric acid strong acid |
| H2SO4 | Suluric Acid strong acid |
| LiOH | Lithium Hydroxide strong base |
| NaOH | Sodium Hydroxide strong base |
| KOH | Potssaium Hydroxide strong base |
| Ba(OH2) | Barium hydroxide strong base |
| CH3COOH | ethanoic acid weak acid |
| H2PO4 | Phosphoric acid weak acid |
| NH3 | ammonia weak base |
| Strong acids and strong bases | high concentration of ions dissociate almost completely |
| Weak acids and bases | dissociate only partially in solution |
| Electrical conductivity | Strong acids and strong bases have higer conductivity than weak acids and bases |
| Rate of reaction | syrong acids react faster |
