Calculate the pH of the acetate buffer after 4 mL of 0.100 M HCl has been added. Acetate buffer is made with 0.160 M NaC2H3O2 & 0.200 M HC2H3O2. We also took 10 mL of acetate buffer and diluted with 30mL of distilled water at the beginning. Ka of HC2H3O2 is 1.8 x 10^-5. I tried doing the SRF table and the pH I got was higher than the pH at the beginning so I know I am doing something...

Calculate the pH of the acetate buffer after 28.00 mL 0.100 M HCl has been added. There is 10 mL of the acetate buffer (0.16 M NaC2H3O2 / 0.2 M HC2H3O2) mixed with 30 mL of water in the buffer solution. The Pka of the buffer is 4.74. Ka = 1.76 x 10^-5 Please help, I've made ICE tables and tried using ph = pka +log (base/acid) and the pH I get is bigger than it should be. As more...
