A beaker with 160 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 7.00 mL of a 0.410 M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.
You titrate a 0.1000 M solution of a strong base (NaOH) with a 100.00 mL solution of 0.1000 M Formic acid (Ka = 1.80 x 10^-4). Calculate the pH at the following points 100.0 mL of NaOH added
