HPO4^2- + H3O^+ <-> H2PO4^- + H2O

basically, if H3O^+ are present, it will shift the equilibrium to the right and uses up the excess H3O^+ ions, thus maintaining pH neutrality.
not sure if you can say that water produced can also help dilute the acid :worried:

anyway, hope this helps ;)

nahh dont think u can

adding OH- ions would neutralise H30+ making more water....

i dunno i hate buffers

lazarus or sumone help...

We have to know about specific buffers and where they are found in nature but I don't think the syllabus specifys the blood buffer system

you're right quartic, the syllabus does not exactly specify the blood buffer system.........so i just chose the easy example in conquering chem. about CO2 and HCO3- buffer in lakes.

Thickett has a very detailed discussion of the blood buffer.
