Concentrated $$H_{2}SO_{4}$$ cannot be used to prepare HBr or HI from KBr or KI because it
Sulphur trioxide is dissolved in heavy water to form a compound X. The hybridisation state of sulphur in X is :
heavy water is D2O i.e Deutrium oxide isotope of hydrogen not H2O
SO3+D2O→D2SO4SO3+D2O→D2SO4

Concentrated $$H_{2}SO_{4}$$ cannot be used to prepare HBr or HI from KBr or KI because it
Oleum on hydrolysis gives sulphuric acid.
