We want to concentrate an acid waste coming from a nitrating process. The acid-in-water waste is 15wt% HNO3, 45wt%H₂SO4 and 40wt% -H₂O. The objective is to obtain a 3000kg concentrated waste that is 25wt% HNO3 and 50wt% H2SO4. Two acid-in-water solutions HNO3-H₂O and H₂SO4-H₂O that have the same acid concentration are used to concentrate the original waster. Determine the mass of H₂SO4-H₂O to be used if 583 kg of HNO3- H₂O have already been added.
