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

H<sub>2</sub>PO<sub>4</sub><sup>-</sup><sub> (aq)</sub> + H<sub>2</sub>O<sub> (l)</sub> <---> HPO<sub>4</sub><sup>2-</sup><sub> (aq)</sub> + H<sub>3</sub>O<sup>+</sup><sub> (aq)</sub>
