Abeaker with 1.60×102 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 7.10 ml of a 0.460 m hcl 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) δph = previous answers incorrect; try again; 16 attempts remaining provide feedback.
