Sulfate can be determined by precipitating barium sulfate with excess barium ion and titrating the excess with EDTA. A 0.4326g sample containing sulfate is dissolved, then precipitated by adding 50.00ml of 0.03150 M BaCl2. After removal of the BaSO4 by filtration, the excess Ba2+ was titrated with 26.38ml of 0.01822M EDTA. Calculate the percentage of SO4 in the sample.

Barium sulfate is only sparingly soluble in water. When excess solid barium sulfate is placed in contact with water to form a saturated solution, the following equilibria are established: 1) BaSO4(s) <---> Ba 2+(aq) + SO4 2-(aq) 2) SO4 2-(aq) + H2O(l) <---> HSO4-(aq) +OH- (aq) 3) 2H2O (l) <---> H3O+(aq) +OH-(aq) Will the concentration of Ba2+ ion increase, decrease, or remain the same when each of the following is done? Explain your reasoning. a) solid sodium sulfate is added...

An unknown amount of acid can often be determined by adding an excess of base and then "back-titrating" the excess. A 0.3471 g sample of a mixture of oxalic acid, which has two ionizable protons and benzoic, which has one, is treated with 94. mL of 0.1060 M NaOH. The excess NaOH is titrated with 21.00 mL of .2080 M HCl. Find the mass % of benzoic acid.

The concentration of CO2 in air is determined by an indirect acid– base titration. A sample of air is bubbled through a solution containing an excess of Ba(OH)2, precipitating BaCO3. The excess Ba(OH)2 is back titrated with HCl. In a typical analysis a 3.5-L sample of air was bubbled through 50.00 mL of 0.0200 M Ba(OH)2. Back titrating with 0.0316 M HCl required 38.58 mL to reach the end point. Determine the ppm CO2 in the sample of air given...

1) a. Write the balanced molecular equation that occurs for the complete reaction of sulfuric acid with sodium hydroxide. b. To determine the molarity of your final sulfuric acid solution, you titrate the final solution with a standardized sodium hydroxide solution to the second equivalence point. If 26.32 mL of 0.1000 M sodium hydroxide was required for complete reaction with 10.00 mL of the final sulfuric acid solution, determine the molarity of the final sulfuric acid solution precisely to four...
