If I want to make a potassium phosphate buffer solution, could I use KOH and H3PO4 instead of KH2PO4 and K2HPO4?

29 January 2021 0 511 Report

Most of the recipes I see for phosphate buffers revolve around using the mono and di-basic salts of the acid.

Since all the potassium phosphate salts can be synthesized from potassium hydroxide and phosphoric acid, could a buffer simply be made by using the acid and base in the correct molar ratio?

Thanks
