Explain equivalence point or gravimetric determination

Reference no: EM13343158

Equivalence point = 0.088 mL, Mass of filter paper+precipitate = 1.05 g, mass of filter paper = 0.82 g, Mass of precipitate = 0.23 g ; Conductivity = 308 microS/cm ; Theoretical E.P. = 10

1. Use the titration results to calculate the moles of H2SO4 that were used to reach the equivalence point in each trial.

2. Use your 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 BaSO4 from 3 above to calculate the molarity of the Ba(OH)2 solution.

5. Compare the results of your calculations from 2 and 4 above with the actual molarity of the Ba(OH)2 solution. Which method of analysis, equivalence point or gravimetric determination, was more accurate in your experiment? Why?
