Question
The spent acid from a nitrating process contains 33% H2SO4, 36% HNO3 and 31% H2O by
weight. This acid is to be strengthened by addition of concentrated sulphuric acid containing
95 % H2SO4 and concentrated nitric acid containing 78 % HNO3. The strengthened mixed
acid is to contain 40 % H2SO4 and 43 % HNO3. Calculate the quantities of spent and
concentrated acids that should be mixed together to yield 1500 kg of the desired mixed acid.
