In order to refine “blister copper” it is metled in a furnace and is stirred with green logs of wood. The purpose is

A

To expel the dissolved gases in blister copper

B

To bring the impurities to surface and oxidize them

C

To increase the carbon content of copper

D

To reduce the metallic oxide impurities with hydrocarbon gases liberated from the wood

Text Solution

Verified by Experts

The correct Answer is:
D
`2Cu_(2)S + 3O_(2)rarr 2Cu_(2)O +2SO_(2)`
`3Cu_(2)O + underset(("From green logs of wood"))(CH_(4))rarr6CU+ 2H_(2)O + CO`
