Blister copper is refined by stirring molten impure metal with green logs of wood because such a wood liberates hydrocarbon gases (like CH4). This process is called X and the metal contains impurities of Y. X and Y are
- X = cupellation, Y = CuO2
- X = polling, Y = Cu2O
- X = polling, Y = CuO
- X = cupellation, Y = CuO
Answer
(B) X = polling, Y = Cu 2 O
