Consider an analyte solution of 50.0mL of 0.050M hydrochloric acid, HCl, titrated against 0.10 M sodium hydroxide, NaOH (the titration you will be performing in the lab!). (d) After adding 12.50mL of the NaOH, halfway to the equivalence point, what ions or molecules are present in the solution? (e) At the equivalence point, after adding 25.00mL of NaOH, what ions or molecules are present in the solution? (f) Which of the species you identified in part (e) will determine the pH of the solution?
