WebMar 24, 2024 · Generally speaking, the effective pH range of buffer is about pKa ± 2ph unit, and to obtain strong enough buffer capacity, the pH is preferably between pKa ± 0.5ph unit. When the ratio of weak acid (or weak base) to the amount of corresponding salt is close to 1:1, the buffer capacity of this buffer system is the strongest. WebBy considering the titration curve for H 3 PO 4 with NaOH ― presented in some chemistry textbooks ― it can be seen that between pH approx. 4.5 and 9.5 the sodium phosphate content is chiefly ...
