Date Performed: 9/26/2011 Ann Forrest Date Submitted: 10/03/2011 Partner: Michael Asselanis Instructor: Emily Klein Stoichiometry Objective: To determine the stoichiometry of the reaction between sodium hypochlorite (NaClO) and potassium iodide (KI) in aqueous solution Experimental Data: Volume of NaClO(mL) Volume of KI(mL) Temperature of NaClO (°C) Temperature of KI (°C) Final Temperature (°C) 45.0 5.0 21.40 20.89 24.37 40.0 10.0 21.24 20.92 27.67 35.0 15.0 21.36 21.32 27.60 30.0 20.0 21.38 21.62 26.63 25.0 25.0 21.59 21.35 25.87 20.0 30.0 21.33 21.35 24.68 15.0 35.0 21.28 21.42 23.56 10.0 40.0 21.25 21.05 22.70 5.0 45.0 20.85 21.30 21.94 Mass of beaker: 49.18mass of beaker+KI: 65.81 mass of KI: 16.63 Sample Calculation: Weighted temperature: T initial = (T 1 V 1 ) + (T 2 V 2 )/ (V 1 +V 2 ) T initial = ((21.40°C)(45.0mL NaClO))+(20.89°C)(5.0mL KI))/(45.0mL NaClO+ 5.0mL KI) T initial = 21.35°C Mole Fraction: Mole Fraction NaClO= Volume of NaClO/ Volume NaClO + Volume KI
