Oleum is considered as a solution of S03 in H2S04 , which is obtained by passing 803 in solution of H2SO4. When 100 g sample of oleum is diluted with desired weight of H20 then the total mass of H2SO4 obtained after dilution is known as % labelling in oleum.
For example, a oleum bottle labelled as '109% H2SO4 means the 109g total mass of pure H2SO4 will be formed when 100 g of oleum is diluted by 9 g of Hp which combines with all the free 803 to form H2SO4 as 
S03 + H20 → + H2SO4.
Q.
What is the % of free S03 in an oleum that is labelled as '104.5% H2SO4’?
  • a)
    10
  • b)
    20
  • c)
    40
  • d)
    Noneof these
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Oleum is considered as a solution of S03 in H2S04 , which is obtained ...
SO3 + H2O →H2SO4. ;
                                18 g water combines with 80 g SO3
                                ∴ 4.5 g of H2O combines with 20 g of SO3            
                                ∴ 100 g of oleum contains 20 g of SO3 or 20% free SO3
