As we learnt in 

Preparation of Sulfur dioxide -

In laboratory, it is prepared by heating copper turnings with conc.H2So4

- wherein

Cu+2H2SO4\rightarrowCuSO_{4}+SO2+2H2O

 

Sulphur dioxide is produced in the laboratory by heating copper turnings with conc. H2SO

Cu+ 2H2SO\rightarrow CuSO_{4}+SO2+2H2O
