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
