Asolution is prepared by dissolving 0.23 mol of benzoic acid and 0.27 mol of sodium benzoate 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 drop slightly. the ph does not decrease drastically because the naoh reacts with the _present in the buffer solution. the ka of benzoic acid is 1.36 x 10-3 a) h20 b) h30+ c) benzoate ion d) benzoic acid e) this is a buffer solution: the ph does not change upon addition of acid or base.
