Van't Hoff's factor for a dilute solution of K3[Fe(CN)6] is — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

K3[Fe(CN)6] is a strong electrolyte that undergoes complete dissociation in dilute aqueous solution: K3[Fe(CN)6] → 3 K^+ + [Fe(CN)6]^3-. Since 1 mole produces 4 moles of ions, the van 't Hoff factor i = 4.0.
