A beaker with 155 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 buffe 0 100 M A student adds 4 10 mL of a 0 310 MHCl solution to the beaker How much will the pH change The pK of acetic acid is 4 740 Express your answer numerically to two decimal places Use a minus sign if the pH has decreased
