Calculate the pH of the acetate buffer after 28.00 mL 0.100 HCl has been added. 10 mL of acetate buffer (Ka = 1.8 x 10^-5): 0.160 M NaC2H3O2 / 0.200 M HC2H3O2
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...
