Conjugate Base Of H2po4
What is the conjugate base of H2PO4? 3
a) HPO4 2
B) H3PO4
c) PO4 3
d) H3O +
E) Oh
My mock test says the answer is b. But as I see it, after a Google search, they say yes. So I don't know what the correct answer is.
Since Bronsted generally views bases as proton acceptors (H +), we only need to know what causes H2PO4 to be caused by a low hydrogen. Since there are only 2 hydrogen atoms left, we will remove only one (H +), which will reduce the charge to 1.
So we have (a) HPO4 2.
