Leaching of copper from cuprous oxide in aerated sulfuric acid

The dissociated cuprous ions (Cu + ) transformed into elemental copper (Cu 0 ) or cupric ions (Cu 2+ ) owing to the instability of Cu + in H 2 SO 4 . Cu + can be reduced to elemental copper (Cu 0 ) by accepting an electron generated from the oxidation of another Cu + to Cu 2+,which is known as a “disproportionation reaction.”
