The initial buffer pH was 6.71 and after addition of the NaOH the pH was 6.73. When weadded the NaOH to the DI water with initial pH of 6.48 the DI water pH increased significantly and changed the pH to 11.49. The initial buffer pH was 6.71 and after addition of the HCl the pH was 6.60. When we added the HCl to the DI water with initial pH of 6.48 the DI water pH decreased significantly and change the pH to 2.61.
