1) A buffer solution contains 0.308 M acetic acid and 0.295 M sodium acetate . If 0.0437 moles of sodium hydroxide are added to 225 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume does not change upon adding sodium hydroxide. ) pH =
2) A buffer solution contains 0.348 M KH2PO4 and 0.380 M Na2HPO4. If 0.0205 moles of nitric acid are added to 125 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume change does not change upon adding nitric acid) pH =
3) A buffer solution contains 0.390 M ammonium bromide and 0.234 M ammonia. If 0.0252 moles of sodium hydroxide are added to 225 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume change does not change upon adding sodium hydroxide) pH =
