Vedclass · Answer

(D) The process of refining blister copper using green logs of wood is known as $poling$. Green logs of wood release hydrocarbon gases (like $CH_4$) upon heating. These gases reduce the cuprous oxide $(Cu_2O)$ impurities present in the blister copper back to metallic copper $(Cu)$. The reaction is: $3Cu_2O + CH_4 	o 6Cu + 2H_2O + CO$.

In order to refine "blister copper",it is melted in a furnace and stirred with green logs of wood. The purpose is:
