Asked by Cat
a. According to the Henderson-Hasselbalch equation, how many grams of sodium acetate will you need to add to 125 mL of 0.100 M acetic acid to make a pH=4.74 buffer?
b. What is the actual pH of the resulting buffer when you add that many grams of sodium acetate to 125 mL of 0.100 M acetic acid?
c. If I want to make the buffer by adding 0.100 M NaOH instead of sodium acetate, how many milliliters of NaOH are needed to reach pH=4.74?
d. If I add enough water to the above buffer to make the total volume 1.00 L, what's the new pH?
e. How many milliliters of 0.25 M HCl will be needed to change the pH of the dilute buffer by 1 pH unit?
