How are SO_(2)Cl_(2) and SO_(2) obtained from sulphuric acid ? – InterviewSolution

1.	How are SO_(2)Cl_(2) and SO_(2) obtained from sulphuric acid ?
Answer» Solution :`SO_(2)Cl_(2)` is FORMED from `H_(2)SO_(4)` by treating with excess of phosphorus PENTACHLORIDE. `H_(2)SO_(4)+2PCl_(5)rarrSO_(2)Cl_(2)+2HCl+2POCl_(3)` `SO_(2)` is OBTAINED from `H_(2)SO_(4)` when heated with copper METAL. `2H_(2)SO_(4)+Cu rarr CuSO_(4)+2H_(2)O+2SO_(2)`
