Problem 3
Creating a 0.1 Normal Solution
Suppose you must determine the amount of hydrogen
halides (HCI, HBr and HF) in the flue gas leaving a
chemical reactor. The emission sampling train for
hydrogen halide determination calls for a total of 200
mL of 0.1 N H₂SO4 as an absorbing solution. The
absorbing solution will be located on the impingers of
the sampling train. How many grams of H₂SO4 should be
added to water to create 200 mL of a 0.1 N H₂SO4
solution?
