A buffer is prepared with NaH2PO4 and Na2HPO4. What is the correct net ionic equation describing what happens when a small amount of NaOH is added to the buffer? a) H3PO4(aq) + OH(-)(aq) → Na2HPO4(aq) + H2O(l) b) NaH2PO4(aq) + NaOH(aq) → Na2HPO4(aq) + H2O(l) c) NaH2PO4(aq) + OH(-)(aq) → Na2HPO4(aq) + H2O(l) d) H3PO4(aq) + NaOH(aq) → NaH2PO4(aq) + H2O(l)
