Calculate buffer capacity instantly. Enter acid/base concentrations and pKa to determine pH resistance. Essential for lab work, pharma formulations & research.
Buffer Capacity
Enter all values to calculate
β = 2.303 à C à Ka à [H+] / ([H+] + Ka)²
Where C is the total concentration, Ka is the acid dissociation constant, and [H+] is the hydrogen ion concentration.
The graph shows buffer capacity as a function of pH. Maximum buffer capacity occurs at pH = pKa.
