3.45 The waste acid from a nitrating process contains 20% HNO3, 60% H2S04 and 20% H20 by weight. The acid is to be concentrated to contain 25% HNO3 and 60% H2SO4 by the addition of concentrated 95% H2SO4 and concentrated 90% HNO3. Calculate the weight of waste acid and concentrated acids, which must be mixed to obtain 5000 kg of desired composition. 3.45 The waste acid from a nitrating process contains 20% HNO3, 60% H2SO4 and 20% H2O byweight.
