Question

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

• A. Both Statement I and Statement II are correct.
• B. Both Statement I and Statement II are not correct.
• C. Statement I is correct but Statement II is not correct
• D. Statement I is not correct but Statement II is correct.

Answer 1

The Correct Option is B

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: 

1. 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.
2. 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.
