Procedure: First, we knew which chemical we were preparing Buffer on which was potassium phosphate buffer (KHP04). Then we calculated the mass of the buffer which was 5.44 grams. Then we weighed out exactly 5.44 grams of the buffer and put it into a 600mL beaker. Next, we added 200 mL of water (H20) to the beaker and dissolved the buffer completely. The pH of the solution was taken, and the pH was 3 which meant that the solution was too acidic. To bring the solution to a pH of 7.3, we added 191 mL of NaOH into the beaker. The pH was 10. Then, we added 81 mL of HCL to the beaker, and the pH was 7.37. The buffer in the beaker was then put into a bottle and labeled with our initials, the date, and the name KHP04 buffer pH 7.37. The bottle was
