Part A A beaker with 1.40x10? 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 butfer is 0.100 mol L-, A student adds 4.90 mL of a 0.480 mol L- HCl solution to the beaker. How much will the pH change? The pK, of acetic acid is 4,760. Express your answer numerically to two decimal places. Use a minus (-) sign if the pH has decreased. > View Available Hint(o) ? ApH =
