Problem- You have 875 mL of an 0.51 M acetic acid solution. What volume (V) of 2.30 M NaOH solution must you add in order to prepare an acetate buffer of pH = 4.33? (The pKa of acetic acid is 4.76.)
Rework your solution from the beginning and check each step carefully.
A beaker with 120 ml of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.40 ml of a 0.250 M HCl solution to the beaker. How much will the pH..
