The purpose of a buffer in a biological system is to maintain intracellular and extracellular pH within a very narrow range and resist changes in pH in the presence of internal and external influences. Rinse the sensor and calibration cup with a small amount of pH 4 buffer solution. An important point that must be made about this equation is it's useful only if stoichiometric or initial concentration can be substituted into the equation for equilibrium concentrations. The value 7 is neutral meaning the amount of H+ in a solution is equal to the amount of OH- in a solution. If the concentrations of acetic acid and acetate are equal, the buffer's pH is 4.76.
