Re: Midterm
it's the second deprotonation of h3po4
the first would include h2po4- in the product, the second will include hpo4^2- in the product

Re: Midterm
Ka2 is the Ka for taking away the second hydrogen in H3PO4
the reaction would be
H2PO4(-) + H2O = HPO4(2-) + H3O(+)
and Ka2 would be
(HPO4(2-)*H3O(+))/H2PO4(-)
the reaction would be
H2PO4(-) + H2O = HPO4(2-) + H3O(+)
and Ka2 would be
(HPO4(2-)*H3O(+))/H2PO4(-)

Re: Midterm
Ka2 is the second deprotonation, when an acid is polyprotic and can give away multiple hydrogens

Re: Midterm
Does anyone know how you would've figured out the oxidation states of the reactants and products involved?
