4. Formic acid, HFor, has a K, value of 1.8 x 10-. You need to prepare 125 mL of a buffer hav- ing a pH of 3.25 from 0.10 M HFor solution and a 0.10 M NaFor solution. How many mL. of NaFor and HFor should be mixed to make the desired buffer? ml. NaFor ml. HFor 5. When five drops of 0.10 M NaOH were added to 20 mL of the buffer in question 4, the pH went from 3.25 to 3.31. Write a net ionic equation to explain why the pH did not go up more than this.
