Van’t Hoff’s factor for a dilute solution of is — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Potassium ferricyanide, $\text{K}_3[\text{Fe(CN)}_6]$, is a strong electrolyte that dissociates completely in a dilute solution into 3 $\text{K}^+$ ions and 1 $[\text{Fe(CN)}_6]^{3-}$ ion. Thus, it produces 4 particles per formula unit, giving $i = 4.0$. Therefore, correct answer is A.
