Webb14 feb. 2016 · H 2P O− 4 + H 2O ⇌ H P O2− 4 + H 3O+. The next step to consider in this problem will be to determine the buffering range of the two buffer systems. For acetate buffer, the pKa value of acetic acid is equal to 4.7 so that getting pKa ± 1, the buffer is suitable for a pH range of 4.7 ± 1 or from 3.7 to 5.7. Meanwhile for phosphate buffer ...
