Experiment #9 REPORT SHEET Name______________________ Date _____________ Lab Partner_________________ Section___________ DATA TABLES Part I * Calculate the molar amounts of NaOH used in the reaction with the HCl solution and with the HC 2 H 3 O 2 solution. ^ Calculate the molar concentration (molarity) of the HCl solution and the HC 2 H 3 O 2 solution. # Compare the actual molar concentrations of your two acid solutions with your calculated molarities. Were the calculated molarities of your acid solutions within a reasonable range (about 5%) of the actual values? If not, suggest reasons for the inaccuracy. DATA TABLES PART II 77 Titration run 1 2 3 4 Intital buret reading (mL) Final buret reading (mL) Volume of NaOH Moles of NaOH* Moles of acid^ Concentration of Acid % error # HCl Trial Volume HCl (mL) Equivalence point (mL) HC 2 H 3 O 2 Trial Volume HC 2 H 3 O 2 (mL) Equivalence point (mL) 1 1 2 2 Titration run 1 2 3 Grams of acid (g) Intital buret reading (mL) Final buret reading (mL) Volume of NaOH Moles of NaOH* Moles of acid^ Molar mass of acid (g/
