How does the blood’s phosphate buffer behave when an hydronium ion is

encountered?

HPO4 2− destroys the hydronium ion and becomes H2PO4 - – and blood pH decreases very slightly
H2PO4 - destroys the hydronium ion and becomes HPO4 2− and blood pH decreases very slightly

A: Mono-hydrogen phosphate is the species that destroys acid (by

accepting a hydrogen ion from the acid). Blood pH would decrease very slightly

as the concentration of mono-hydrogen phosphate decreases slightly and the

concentration of di-hydrogen phosphate increases slightly.
