Sample problem 6 (Exam style question) A company operates a batch process that uses sulfuric acid. At the end of each batch, the leftover acid must be diluted before it is released. The amount of water to be added to enable this dilution is carefully calculated following analysis of the leftover sulfuric acid in the batch liquid. The terms of the discharge licence state that there should be no more than 1.00 g L- of sulfuric acid in the discharge water. A 25.00 mL sample of the batch liquid was accurately diluted to 250.0 mL in a standard flask. 25.00 mL of this diluted sample was then titrated with 0.100 M standardised sodium hydroxide solution using a suitable indicator. An average titre of 18.52 mL was obtained. a. Write the equation for the reaction between sodium hydroxide and sulfuric acid. b. Calculate the number of moles of sodium hydroxide that were added. C. From your answer to part (b), calculate the number of moles of sulfuric acid in the diluted sample. d. Hence, calculate the molarity of sulfuric acid in the diluted sample. e. Calculate the molarity of sulfuric acid in the undiluted batch liquid. f. Calculate the molarity of the sulfuric acid that is allowed in the discharge water. g. Hence, calculate the volume of water, in L, that must be added to each litre of batch liquid to meet the terms of the discharge licence. Give your answer to 1 decimal place
