Answer

The production of sulphur dioxide calls for the utilization of copper turnings as well as concentration. The production of sulphur dioxide calls for the utilization of copper turnings as well as concentration. By gently running inert gas supplies over hot copper turnings at a temperature of 600K, one can use the turnings as a "oxygen getter" for the inert gas supplies. Copper sulate, sulphur dioxide, and water are the products obtained from the reaction of concentrated sulphuric acid with copper turnings. Cu+2H2SO4hat−−−→CuSO4+SO2+2H2O
