Cell Compounds
Water Acids Base and Buffers
| Question | Answer |
|---|---|
| Acids | Molecules that have a PH less than 7, disassociate in water and release H+ (hydrogen molecules) |
| Bases | Molecules that have a PH greater than 7, release OH- (Hydroxide) or absorb excess H+ (hydrogen) |
| Buffers | A compound or compounds that keep the PH of a solution with in a its normal limit; often a weak Acid or Base |
| Hemoglobin | A buffer found in blood that releases O2 (oxygen) and absorbs C02 (carbon dioxide) and H+ (hydrogen) |
| Hydrogen Bonding | A weak bond between water molecules formed by the opposite charges atoms O (oxygen) and H+ (hydrogen) |
| Hydophilic | Water loving molecules that are polar in nature |
| Hydrophobic | Water-phobic molecules that are not polar |
| Lubricant | Substance used to minimize friction eg. water in blood |
| PH | Relative strength of a acid 0 being Acidic, 7 being neutral and 14 being Basic |
| Polarity | The charge of a molecule |
| Solvent | Liquid component of a solution |
| Temperature Regulator |
