A solution is prepared by dissolving 0.23 mol of hydrazoic acid and 0.27 mol of sodium azide in water sufficient to yield 1.00 L of solution.The addition of 0.05 mol of NaOH to this buffer solution causes the pH to increase slightly. The pH does not increase drastically because the NaOH reacts with the ________ present in the buffer solution. The Ka of hydrazoic acid is 1.9 × 10-5.

Develop the proton condition (TOTH equation) for a solution prepared from 2x10-3 mol/L NaH2PO4, 5x10-4 mol/L NaOH, 5x10-4 mol/L HAc (acetic acid) and 10-3 mol/L HOCl using the dominant species as the reference species (ZPRL) and find the equilibrium pH. The pKa values for the acid-base pairs are 2.148, 7.198, 12.375 for the orthophosphate system; 7.497 for hypochlorite; and 4.757 for acetate. Also, note OH– (from NaOH) is a strong base with a pKa value of 14.0.
