Poling is a purification process which is used for metals which contains their own oxide as impurity.

Q. Blister copper is refined by stirring molten impure metal with green logs of wood because such a wood liberates hydrocarbon gases (like $C H_{4}$ ). This process X is called __ and it is used to purify the metal that initially contain impurities of Y. Y is _.

X = poling, Y = $C u O_{2}$

X = cupellation, Y = $C u O$

X = cupellation, Y = $Z n O$

X = poling, Y = $C u_{2} O$

Poling is a purification process which is used for metals which contains their own oxide as impurity.

Q. 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 X is called ________ and it is used to purify the metal that initially contain impurities of Y. Y is _______.

X = poling, Y = CuO2​

X = cupellation, Y = CuO

X = cupellation, Y = ZnO

X = poling, Y = Cu2​O
