A solution is prepared by dissolving 0.23 mol of nitrous acid and 0.27 mol of sodium nitrite 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 decreases the present in the buffer solution. The Ka of nitrous acid is 4.5 x 10-4. water sodium ion O nitrite ion nitrous acid O this is a buffer solution, the pH does not change upon addition of acid or base.
