Consider the next two questions together. A 30.0 mL sample of 0.200 M acetic acid is titrated with 0.100 M NaOH. Use the titration curve to predict the main species present when 40 mL NaOH has been added. A 30.0 mL sample of 0.200 M acetic acid is titrated with 0.100 M NaOH. Use the titration curve to predict the main species present when 60 mL NaOH has been added.
