A buffer is prepared by adding 2.78g of potassium acetate to 173mL of 1.25M acetic acid. What is the pH of the buffer? Write the net ionic equation for this buffered solution. (consider pH) How will the pH change if 0.100M HNO3 is added? (Assume volume change is negligible.) How will the pH change if 0.100M KOH is added? (Assume volume change is negligible.) Explain in words what would happen if .200M of HNO3 is added?
