Buffer Lab Report. 1344 Words6 Pages. Introduction. Buffer is a solution that resists a change in pH when bases or acid are added. Solutions that are acidic contain high concentrations of hydrogen ions (H+) and have pH values less than seven. Buffer usually consist of a weak acid, and its conjugate base or a weak base and its conjugate acid. Normally phosphate is the only buffer in urine, although carbonic acid/ bicarbonate is also present. The developing urine contains NaH2PO4/Na2HPO4 in the same concentration as present in blood plasma.
