David (Luke) Smith CHE 111-016 Fariba Karimi 11-6-11 Matt Perry The Titration of Acid-Base Introduction to Titration Goal of Lab Students learn what titration means and how to do it. To learn what an equivalence point is and how to read it using a graph Calculation of the molarity of a substance Balance out equations using stoichiometry Procedure for titration lab The procedure is in the lab manual. (Soult, pgs. 71-82) Titration of Acid-Base Discussion In this experiment there was a acid and a base mixed. The molecular equation for the titrations performed in the lab was: HCl (aq) + NaOH (aq) NaCl (aq) + H 2 O (l) The ionic equation of the molecular equation was: H + (aq) + Cl - (aq) + Na + + OH - Na + (aq) Cl - (aq) + H20 (l) The Net Ionic equation of the molecular equation was: H + (aq) + OH - (aq) H20 (l) In the experiment, there were two titrations performed. The hypothesis was that as HCl is titrated with NaOH the pH value of the acidic solution will be initially low. As
