Alex RadzinProfessor ChanduCHM 266 Section 1210/23/17Conductimetric Titration and Gravimetric Determination LabIntroduction:In this lab, the conductivity of the reaction between H2SO4and Ba(OH)2was measured. The conductivity values were then used to determine the equivalence point of the reaction. The mass of the product of the reaction was measured as a means of determining the equivalence point of the reaction. Once that was finalized, the molar concentration of Ba(OH)2solution was calculated.50 mL of distilled water was added to a 250 mL beaker that contained 10 mL of Ba(OH)2. The conductivity probe was set up and placed in the mixed solution. A 60 mL reagent reservoir was added to the ring stand, it was rinsed out with a few mL oh H2SO4, and then filled with 60 mL of H2SO4. The solution of Ba(OH)2was put on a magnetic stirrer and then a metallic pill was placed in the solution to stir it. Slowly, the HCl was added to the stirring solution while the LabQuest graphed it. Then the solutionwas heated up forming a Ba(OH)2. It was filtered then that was heated on top of a beaker that contained boiling distilled water. The filter paper was weighed and recorded.The graph was supposed to decline slowly, reach the equivalence point, and spike back up. The graph was supposed to make a “v” shape. The masses of the filter paper, precipitate, and the two together were recorded. Then the molarity of H2SO4
