1) Calculate the pH of the 1L buffer composed of 500 mL of 0.60 M acetic acid plus 500 mL of 0.60 M sodium acetate, after 0.010 mol of HCl is added (Ka HC2H3O2 = 1.75 x 10-5). Report your answer to the hundredths place. 2) Calculate the pH of the 1L buffer composed of 500 mL 0.60 M acetic acid plus 500 mL of 0.60 M sodium acetate, after 0.010 mol of NaOH is added (Ka HC2H3O2 = 1.75...
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...
