WebActually in blood the buffering of carbonic acid is complicated by the presence of the red cells: 6. Uses of Buffers: i. Buffers are used for preparing standard solutions in which it is always desired to maintain a constant pH. This is required for the colorimetric determination of the pH of unknown solutions. WebHumans are sensitive to changes in blood pH, and pH levels above 7.8 or below 6.8 can kill you. Under normal circumstances, your body uses phosphate in a system of chemical buffers designed to combat any significant changes in blood pH. However, hard alcohol in particular decreases the effectiveness of the buffer system.
