Question

The Vant Hoff factor (i) for a dilute solution of $K_3\left[Fe\right(CN{)}_6]$ is (Assuming $100\%$ ionsation):

• A. $10$
• B. $4$
• C. $5$
• D. $0.25$

Answer 1

The correct option is B $4$

The Vant Hoff factor (i) for a dilute solution of $K_3\left[Fe\right(CN{)}_6]$ is $4$. It dissociates to give $3$ potassium ions and $1\left[Fe\right(CN{)}_6{]}^{3-}$ ion.
