How many moles of O2 are in one mole of H3PO4? Actually H3PO4 is a molecular formula referring to the compound we know as Phosphoric acid. It doesn't indicate number of moles of H3PO4.
It depends on the concentration. pH is the negative log of the concentration of H+ atoms in a solution (measured it molarity, mol/L). Phosphoric acid (H3PO4) has 3 Hs in it, so for every molecule ...

Question: Phosphoric acid, H3PO4, is tribasic with pKa values of 2.14, 6.86, and 12.4. The ionic form that predominates at pH 3.2 is: H3PO4 + H2O ⇌ H3O+ + H2PO4 - ⇌ H3O+ + HPO4 2- ⇌ H3O+ + PO4 3- The answer is H2PO4- Can you explain the concept/reasoning behind this?
The formula* for phosphoric acid is H3PO4.*Compounds do not have "symbols" in the chemical sense; only atoms do. The formula itself, of course, is a symbol for the compound itself in a more ...
