# The reaction between copper and hot concentrated sulfuric acid produces : Option 1) $So_{2}$ Option 2) $So_{3}$ Option 3) $H_{2}$ Option 4) $Cu^{+} ions$

As we learnt in

Preparation of Sulfur dioxide -

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

- wherein

Cu+2H2SO4$\rightarrow$$CuSO_{4}$+SO2+2H2O

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