Which of the following statements is correct regarding the slag obtained during the extraction of iron?

Options

  1. AThe slag is lighter and has lower melting point than the metal.
  2. BThe slag is lighter and has higher melting point than the metal.
  3. CThe slag is heavier and has lower melting point than metal.
  4. DThe slag is heavier and has higher melting point than the metal.

Correct answer

A. The slag is lighter and has lower melting point than the metal.

Step-by-step solution

Slag formed during the extraction of iron is always lighter than the molten metal. Its melting point should also be less than the molten metal.
