Potassium phosphate buffer 역할

WebNormalizing the amount of each of the four phosphate moieties, their relative amounts are calculated. Knowing that the absolute amounts of the phosphate species sum to the buffer strength, the absolute concentrations can be calculated. Then, because the total charge in the buffer must be zero, the sodium ion concentration can be obtained.
