Which statement below is correct regarding the pH meter exercise: Students are required to Solve both Buffer problems from Set A in the lab manual, make the buffers, and measure the pH of both buffers Your TA will assign you a buffer problem from Set A in the lab manual to solve. This buffer must be made and the pH must be measured. After measuring the pH, a drop of 0.1N HCl is added and the pH is re-measured. The pH would be expected to decrease. Your TA will assign you a buffer problem from Set A in the lab manual to solve. This buffer must be made and the pH must be measured. After measuring the pH, a drop of 0.1N HCl is added and the pH is re-measured. The pH would be expected to be relatively constant (very minimal change)
