The Ka values of H3PO4 are shown below.
Ka1 7.5 10-3
Ka2 6.2 10-8
Ka3 4.8 10-13

What is the pH of a 0.19 M solution of NaH2PO4?

  • Chemistry -

    (H^+) = sqrt(k1k2)

  • Chemistry -

    How come it didn't matter what the molarity was? It wasn't used at all.

  • Chemistry -

    same question. why wasn't the molarity used>?
