An aqueous 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.
◦ H2O
◦ H3O+
◦ azide
◦ hydrazoic acid
◦ This is a buffer solution: the pH does not change upon addition of acid or base.
