Question- 1) Calculate the pH of the resulting solution with 10.00 mL of 1.500 M HCl is added to 100.0 mL of an aqueous solution that is 0.472 M C9H7N and 0.531 M C9H7NH+Cl.
2) Calculate the pH of the resulting solution with 10.00 mL of 1.250 M NaOH is added to 100.0 mL of an aqueous solution that is 0.472 M C9H7N and 0.531 M C9H7NH+Cl.
I require explanations on how to do these. I remain getting close, but I'm not getting the right answer.
