Which of the following reactions will produce more volatile acid:

Pb(NO3)2  + H2SO4(dil.)  --> PbSO4  + 2HNO3

KNO3 + H2SO4(conc.)  --> KHSO4  + HNO3

Expert Answer:

Dilution increases volatality. So when concentration increases volatality decreases. 
So dilute H2SO4 will prodeuce more volatile acid.
