Question

4 of 12 PartA A beaker with 125 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 4.00 mL of a 0.430 MHCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.740 Express your answer numerically to two decimal places. Use a minus(sign if the pH has decreased View Available Hint(s) Submit Previous Answers X Incorrect; Try Again; 2 attempts remaining Next ) Provide Feedback
