is that the reason why a puffer based on
10 ml of 0,1 M Phosphatpuffer and
100 ml of a 0,01 M Phosphatpuffer
consisting of the same amount of KH2PO4 und K2HPO4
can puffer the same amout of OH as well as H+ (because we would have 0,1*0,1 = 0,01 M protones in the first one; and since we got PO4 in the same amount, we have to calculate nothing here)
Why do they both have the same amount of electrolytes and difer in the concentration of the electrolytes?
