When K4[Fe(CN)6] is dissolved in a solution of salt, then it produces
Correct answer: C. Complex ions and simple ions
- A. Simple ions only
- B. Complex ions only
- C. Complex ions and simple ions
- D. Weak acid HCN
Explanation
When K4[Fe(CN)6] is dissolved in a salt solution, it dissociates into simple ions and complex ions. Specifically, it produces four potassium ions (4K+) and one complex ion ([Fe(CN)6]4-). This dissociation results in the presence of both simple and complex ions in the solution.The other options are incorrect because they either consider only simple ions, only complex ions, or incorrectly suggest the formation of a weak acid, which does not occur in this specific dissociation process.

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.
