The spent acid from a nitration process contains 33% h2so4, 36% hno3 and 31% h2o. this is to be strengthened by the addition of concentrated h2so4 containing 95% h2so4 and nitric acid containing 78% hno3. the final strengths of mixed acid solution contains 40% h2so4 43% hno3 and the rest water. calculate : a. the amount of spent acid
b. the amount of concentrate h2so4
c. thr amount of concentrate hno3 to be mixed to produce 1500 kg of tge desired acid
