When 5 drops of 0.10 M NaOH were added to 20mL of the buffer in problem 3, the pH went from 3.40 to 3.43. Write a net ionic equation to explain why the pH didn't go up to about 10, as it would have if that amount of NaOH were added to distilled water or to 20mL 0.00040 M HCl, which also would have a pH of 3.40? (Buffer from problem 3: HFor has K(a) value of 1.8 x 10^-4. A student is to prepare a buffer having a pH of 3.40 from a 0.10 M HFor and a 0.10 M NaFor solution. How many milliliters of the NaFor solution should she add to 20mL of the 0.10 M HFor to make the buffer)
