Which of the following is not a simple salt?
Correct answer: B. KCl.MgCl26H2O
- A. FeSO4
- B. KCl.MgCl26H2O
- C. Al2(CO3)3
- D. NH4Br.
Explanation
A simple salt is a compound which has been prepared by the combination of two simple ions like Na+ and Cl- ions to form NaCl. Similarly KBr, K2S, MgCl2 CaC2 etc., simple ionic salts. Another set of simple salts can be Zn3P2, V2O5 etc., which are bonded covalently. Salts like FeSO4, Al2(CO3)3, NH4Br etc., are ionic, but formed by the combination of a simple ion and a compound ion such as SO4 2-, CO3 2-, NH4+ etc.

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.
