Question
Which pair of metals can be extracted from their ores using carbon?A:Iron and aluminiumB:Magnesium and potassiumC:Iron and copperD:Copper and sodium
Solution
The pair of metals that can be extracted from their ores using carbon are Iron and Copper. So, the correct answer is C: Iron and Copper.
Here's the step by step explanation:
-
Iron is extracted from its ore, hematite, in the blast furnace. Carbon is used in the form of coke, which is both a fuel and reducing agent. The carbon (coke) reduces the iron ore to molten iron, and the carbon itself is oxidized to carbon dioxide.
-
Copper can also be extracted from its ore by reduction using carbon. The copper ore is heated in a furnace, and the copper(II) oxide is reduced by carbon to copper.
On the other hand, Aluminium is extracted using electrolysis, not carbon. Magnesium, Potassium, and Sodium are also extracted using electrolysis because they are too reactive to be reduced by carbon.
