Madoussou SanogoGeneral Chemistry Lab IIExperiment 17 23 March 2018Buffer SolutionsTitle: Determining if acetic acid/buffer solution can resist changes in pH.Objective:The objective of this experiment is to find the pKaof acetic acid by multiple methods and to determine if the acetic acid/ sodium acetate buffer solution can resist changes in pH.Variables:The independent variable is the pH of the solutions and the dependent variable is the pKaof acetic acid.Hypothesis:In this experiment using methods of titration with NaOH and acetic acid, we will find the pH of a buffer solution. The pKaof acetic acid will be found by measuring the pH of acetic acid, which should be roughly around 2.88. You can then use pH to find the concentration of H3O+using the equation [H3O+] = 10-pHwhich should be 1.3 x 10-3M. Since the concentration of acetate and hydronium are equal we can solve for Kaby multiplying both concentrations and dividing it by the average molarity of acetic acid from the three trials. Then the pK
