To calculate D.V.S. from the mixed-acid analysis the formula is, D.V.S ___________(a) S/(EW/R+W)(b) S/(ES/R+W)(c) S / (ER/ R+W)(d) S / (EN / R+W)I have been asked this question in an internship interview.My enquiry is from Mixed Acids for Nitration topic in division Nitration of Unit Processes

Answer»

Correct OPTION is (d) S / (EN / R+W)

To explain: For calculating the DVS Value the following formula is used : S / (EN / R+W) ,Where: S = percent actual H2SO4,

N = PER CENT actual HNO3

W = per cent WATER

E = water equivalent of material to be nitrated and

R = nitric ratio.
