    • Na 3 PO 4 is the conjugate base of the weak acid H 3 PO 4. I know that Na 3 PO 4 will dissociate into ions in solution, leaving the PO 4 3-ion. If I could add anything to the solution, I would add H 3 PO 4 to the solution to make the buffer, but it is not one of the options. Submitted by spock on Wed, 05/08/2013 - 16:36.
  • Will $\ce{NaH2PO4}$ react as as an acid or a base if you make it react with water? I got stuck here. I can figure out the reaction: $$\ce{NaH2PO4 + H2O -> Na^+ + H2PO4^- + H2O}$$ But when I look $\ce{H2PO4^{-}}$ up, it says that it can both be an acid and a base. Any ideas?

  • How many moles of conjugate base (Na2HPO4) are present in 40mL of .010M buffer at pH 7.5 vs at pH 6? Buffer was made up of Na2HPO4 and NaH2PO4. pH=pKa +log[A/HA]; pKa=7.2.... When I did the calculations I got the same amount as if it were in a 0.1M buffer at the same pH's so I think I'm doing something wrong.
