WebJul 27, 2024 · The phosphate buffer system operates in the internal fluid of all cells. This buffer system consists of dihydrogen phosphate ions (H 2 PO –4 ) as hydrogen ion donor (acid) and hydrogen phosphate ions (HPO 2-4) as hydrogen-ion acceptor (base). These two ions are in equilibrium with each other as indicated by the chemical equation given below.
