Which of the following compounds is sold as fertilizer?
Correct answer: C. Ca3(PO4)2
- A. CaSiO3
- B. Na2SiO3
- C. Ca3(PO4)2
- D. MnSiO3
Explanation
Option A) CaSiO3, also known as calcium silicate, is not typically used as a fertilizer, but it is used in construction materials and insulation.Option B) Na2SiO3, also known as sodium silicate, is used in a variety of industrial applications, including adhesives, detergents, and water treatment, but it is not commonly used as a fertilizer.Option C) Phosphorus fertilizers include calcium phosphate derived from phosphate rock or bones. The more soluble superphosphate and triple superphosphate preparations are obtained by the treatment of calcium phosphate with sulfuric and phosphoric acid, respectively.Option D) MnSiO3, also known as manganese silicate, is not commonly used as a fertilizer, but it is used in the production of glass and ceramics.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
