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)
