- A sulfuric acid spill occurred on the highway after a truck containing barrels of sulfuric acid swerved out of control from a truck tire blowout. Luckily no one got hurt in the event but there is a concern that the sulfuric acid spill may affect local ground water supply. A sample of the ground water in that area was recovered to assess the extent of contamination of the ground water supply. In order to determine the concentration of sulfuric acid in the sample, 25.00 mL of the ground water sample was titrated with 0.133 M NaOH and you get the following data: Sodium hydroxide (initial buret reading) 0.66 mL Sodium hydroxide (final buret reading) 17.42 mL Calculate the molarity of sulfuric acid in the ground water sample.
