Academics

When 5 drops of 0.10 M NaOH were added to 20 ml of the buffer in problem 3, the pH went from 3.60 to 3.71. 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 0.00025 M HCL, which also would have a pH of 3.60
