Solution

The correct option is C molten metal took up small amount of nitrogen which makes the steel brittle
If air is used for the oxidation of pig iron, the molten metal will take small amount of nitrogen. Hence, the steel will be brittle.
Hence, pure oxygen is used instead of air.

_________ is defined as a process where materials, usually metals, deteriorate as a result of a chemical reaction with air, moisture, chemical, etc. For example, iron, in the presence of moisture, reacts with oxygen to form hydrated iron oxide.

The purest form of iron is prepared by oxidising impurities from cast iron in a reverberatory furnace. Which iron ore is used to line the furnance? Explain by giving reaction.

Q. Iron when reacts with moist air forms a reddish brown layer of iron oxide which is known as rust.

Q. Assertion :To protect iron from rusting it is coated with a thin layer of zinc. Reason: The zinc forms a barrier against corrosion in that the steel underneath does not come into contact with water / moisture in the air
