WebThe buffer range is the pH range over which a buffer acts effectively. Buffer capacity - the number of moles of acid or base that must be added to one liter of the buffer solution in order to lower or raise the pH by one unit. The more similar the concentration of the two components, the greater the buffer capacity. WebThe potassium dihydrogen phosphate/di-sodium hydrogen phophate buffer solution is gravimetrically prepared at a registered calibration laboratory with high-quality reagents and water. Its pH value of 6.86 at 25℃ is measured using a combined glass electrode following a 5-point calibration method. The measurement is made following DIN 19268 ...
