Reaction between Sulphuric acid and Copper is very important in lab chemistry. We can use this reaction to make SO_2 or Sulphur Dioxide in the laboratory. 

Copper = Cu

Conc. Sulphuric acid = H_2SO_4

Sulphur Dioxide = SO_2

In the reaction Copper Sulphate`(CuSO_4)` and Water`(H_2O)` would also be formed.

The reaction is as follows.

`Cu_((s))+H_2SO_4_(aq) rarr CuSO_4_(aq)+SO_(2(g))+H_2O_((l))`


The presence `CuSO_4` may change color of the solution to a bluish color.
