What is the reaction between copper and concentrated sulphuric?
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.
