Question

What I have so far for data etc.

Trial 2 T Trial 3 Trial 1 Equivalence point (mL) Mass of filter paper Precipitate (g 32 Mass of filter paper (g Mass of precipitate (g) of H2SO4 Mola DATA ANALYSIS (Show examples of each calculation for credit) 1. Use the titration results to calculate the moles of H.soathat were used to reach the equivalence point in each trial. The equivalence point is most accurately determined from the intersection of he best fit lines of the data points on your plots before and after the equivalence MaA moles conc x vol. 2. Use your titration results to calculate the molar concentration (molarity) of Ba? ion in the ar amount of H2Sou used in each trial. 3. Convert the mass of the barium sulfate precipitate, formed in cach trai to moles. lo37 383 233.38 olarity of the Ba(OH) solution. moles of Ba (OH)2 (A) Baso 36

My question I need help with though is:

This is my data and what I have so far but this is the question I actually need help with:

-What ions are present in the titrated solution after the beginning of the titration but before the equivalence point? How about after the equivalence point when the conductivity is rising? Lastly, compare your results from 2 and 4 above with the actual molarity of the Ba2+ in the solution. Which method of analysis, equivalence point or gravimetric determination, was more accurate in your experiment? Why?
