Explain a beaker with 165 ml of an acetic acid buffer

Reference no: EM13533875

A beaker with 165 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 7.80 mL of a 0.360 M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.
