    Phosphoric acid mixture titration

    oh.. really? I am still not sure because that seems too easy! so.. the volume (and moles) of NaOH added at the first quivalence point will give the moles of H3PO4, and the volume (and moles) of the NaOH added at the 2nd equivalence point will give the amount of H3PO4 + H2PO4-. So i can...

    Phosphoric acid mixture titration

    ok.. and is the calculation for the first end point correct? and if I know that the second endpoint gives the amount for HPO4- from both the sources, how do i actually go about the calculation..? thankss!

    Phosphoric acid mixture titration

    Homework Statement A mixture of phosphoric acid and NaH2PO4 are titrated against 0.151 M NaOH. The first equivalence point is at 0.00345 L and the second equiv point is at 0.01288 M. The volume of the total mixture was 60 ml. Calculate the concentration of both the phosphoric acid...
