An iron(III) coordination compound has the empirical formula K ₂ Fe ( CN )₅( H ₂ O )₃ . In aqueous solution, it acts as a ternary electrolyte (yielding three ions per formula unit) and gives no precipitate with excess AgNO ₃ solution. The magnitude of the crystal field stabilization energy (CFSE) in terms of _o (ignoring pairing energy) and the number of electrons in the e_g orbitals of the complex anion are respecti

Step-by-step solution

The compound acts as a ternary electrolyte, meaning it dissociates into 3 ions in aqueous solution. Since it contains potassium, it likely dissociates into 2 K ^+ and one complex anion with a -2 charge. The absence of a precipitate with AgNO ₃ confirms that there are no ionizable chloride or other precipitating anions outside the coordination sphere (which matches the formula). The charge of the complex anion is -2 . The central metal is Fe(III), which has a +3 charge. The five CN ^- ligands contribute a -5 charge.
