How many moles of H2PO4 and HPO4 would be needed to prepare 1.0 L of a 0.01M phosphate buffer with a pH of 6.82? Use the Henderson-Hasselbalch equation. pH = pKa + log (base)/(acid). Thank you, but I guess what my question should have been is what is the acid in this question ...
Thank you, but I guess what my question should have been is what is the acid in this question and what is the base. I would assume that both H2PO4 and HPO4 are acids and phosphate is the base but Im not sure.
