Vedclass · Answer

(A) The reactions given are:$(i) 2 Cu_2S + 3 O_2 \rightarrow 2 Cu_2O + 2 SO_2$$(ii) 2 Cu_2O + Cu_2S \rightarrow 6 Cu + SO_2$These reactions represent the self-reduction process in the extraction of copper.Due to the evolution of $SO_2$ gas during the solidification of the molten copper,the surface of the metal develops bubbles or blisters.Therefore,the copper obtained is referred to as blister copper.

In the extraction process of copper,the product obtained after carrying out the reactions
$(i) 2 Cu_2S + 3 O_2 \rightarrow 2 Cu_2O + 2 SO_2$
$(ii) 2 Cu_2O + Cu_2S \rightarrow 6 Cu + SO_2$ is called
