3.46 Waste acid from a nitrating process contains 21% HNO3, 55% H2SO4 and 24% H2O by weight. This acid is to be concentrated to contain 28% HNO3 and 62% H2SO4 by the addition of concentrated H2SO4 containing 93% H2SO4 and concentrated nitric acid containing 90% HNO3. Calculate the weight of the waste acid and concentrated acid that must be combined to obtain 500 kg of the desired mixture. 3.46 Waste acid from a nitrating process contains 21% HNO3, 55% H2SO4 and 24% H2O by weight.This acid is to be concentrated to contain 28% HNO3 and 62% H2SO4 by the addition ofconcentrated H2SO4 containing 93% H2SO4 and concentrated nitric acid containing 90% HNO3.Calculate the weight of the waste acid and concentrated acid that must be combined to obtain 500kg of the desired mixture.
