Calculate the theoretical pH after 2.50 mL and 9.50 mL of NaOH has been added in both the titration of HCl and of HC2H3O2.
Given:
Molarity of all chemicals are 0.1 M
HCl and HC2H3O2 are 8ml prepared in 100ml water.
Your post is not clear.
2.50 mL 0.1M NaOH and
9.50 mL 0.1M NaOH is clear.
I don't know what you have titrated.
