A beaker of an acetic acid with 1.00×102mL buffer with a pH of 5.000 is sitting on a bench top. It is found that the 0.100 M is the total molarity of acid and conjugate base in this buffer. A boy mixes 5.70mL of a 0.330M Hydrochloric acid solution to the beaker. Determine the pH change if The pKa of acetic acid = 4.760.
