Buffers are aqueous solutions that tend to resist changes in pH when small amounts of strong acid (H+) or base (OH-) are added. Compare the changes in the pH of the resulting solution when you add 0.1 M NaOH in (a) distilled water and (b) bicarbonate solution. O A) No changes in pH of both solutions. O B) (a) and (b) solutions will have the same pH. O c) pH change in (b) will be higher than in (a). D) pH change in (a) will be higher than in (b).
