Given below are two statements Statement I : Pig iron is obtained by heating cast iron with scrap iron Statement II : Pig iron has a relatively lower carbon content than that of cast iron In the light of the above statements, choose the correct answer from the options given below
Both Statement I and Statement II are not correct.
Statement I is correct but Statement II is not correct
Statement I is not correct but Statement II is correct.
Show Solution
The Correct Option isB
Solution and Explanation
To determine the correctness of the given statements regarding pig iron and cast iron, we need to understand the properties and production methods of each:
Statement I: Pig iron is obtained by heating cast iron with scrap iron.
Incorrect: Pig iron is typically produced in a blast furnace as an intermediary product in the steelmaking process. It is created by smelting iron ore with a high-carbon fuel, such as coke, and a flux, such as limestone. It is not produced by heating cast iron with scrap iron.
Statement II: Pig iron has a relatively lower carbon content than that of cast iron.
Incorrect: Pig iron actually has a higher carbon content than cast iron. Pig iron typically contains 3.5-4.5% carbon, while cast iron generally contains 2-4% carbon.
Based on these explanations, we can see that both Statement I and Statement II are incorrect. Pig iron is distinct from cast iron in its method of production and its carbon content. Therefore, the correct answer is:
Both Statement I and Statement II are not correct.
