Caitlyn AdamsExperiment 18Gen Chem Lab 2Buffer Solutions and pHObjective:The goal of this experiment is to find pKaof acetic acid by multiple methods and to determine if an acetic acid/sodium solution acetate buffer solution is able to resist changes in pH.Hypothesis One:It is anticipated that the pKa of the acetic acid solution will be approximately 4.8. This will be determined through the use of two methods. In the first method, we will perform a titration with acetic acid and sodium hydroxide to find the concentration of acetic acid. From here, a pH meter will be used to determine the pH. The negative antilog of this value will be taken which is the concentration of hydrogen ions and will be plugged into the acid dissociation concentration formula to find ka. From here, the negative log will be taken. This value is the pKa. The second method to determine the pKawill be to make a buffer solution with the concentrationof the acetate ion equal to the concentration of acetic acid so that by the Hnederson-
