In the production of wrought iron Mg Si and P are removed in the form of___________________?

Correct answer: C. slag

  • A. oxides
  • B. silicates
  • C. slag
  • D. carbonates

Explanation

During wrought-iron production, impurities such as magnesium, silicon and phosphorus are oxidised and combine with flux to form a molten waste material called slag. The likely alternative is oxides, because the impurities first form oxides, but these oxides then combine with flux and are removed as slag.

About Electronic Structure of d-Block Elements

The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
