Stuck on this
A beaker with 105 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 6.30 mL of a 0.450 M HCI
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.
