What is the eqn for a buffer equilibrium of:

H2PO4 ^(-) / HPO4^(2-)

in human blood???

I got H2PO4 ^(-) + OH^(-) <--> HPO4 ^(2-) + H2O

It's prob very very wrong. I honestly have no idea what the answer is

More common would be

H₂PO₄^-_(aq) + H₂O_(l) <---> HPO₄^2-_(aq) + H₃O⁺_(aq)

what?!?!?!

H2PO4 a buffer in blood?

i'm pretty sure it's H2CO3

 

[blam_babe]

Apparently it is

I'm pretty sure it's H2CO3.

both occur in blood

 

[blam_babe]

I got it in a qn so I'm guessing that it must be right

True, and there are more than just these two, as well.
