Experiment 9 Conductometric Titration and Gravimetric Determination of a Precipitate REPORT SHEET Name: DATA TABLE Trial 1 Trial 2 Trial 3 Equivalence point (mL) 27.l16 mL Mass of filter paper precipitate ()311 I1133 20139 03228 Mass of filter paper (9) Mass of precipitate (g) Molarity of HaSO (M) DATA ANALYSIS (If you need more space, provide your answers on the back page) 1. Use the titration results to calculate the moles of H2SO4 that were used to reach the equivalence point in each trial. 3.415 X10 nal504 2. Use your r titration results to calculate the molar concentration (molarity) of the Ba(OH)2 solution using the molar amount of H2SO4 used in each trial. 3. Convert the mass of the barium sulfate precipitate, formed in each trial, to moles. 4. Use the moles of BaS0s from 3 above to calculate the molarity of the Ba(OH)2 solution. Ba(OH)2 solution. Which method of analysis, equivalence point or gravimetric determination, was more accurate in your experiment? Why? 5. Compare the results of your calculations from 2 and 4 above with the actual molariy of the 9-5
