Which one of the following salts would have the same value of the Vant Hoff factor (i) as that of K3[Fe(CN)6].
Correct answer: D. Al(NO3)3
- A. NaCl
- B. Na2SO4
- C. Al2(SO4)3
- D. Al(NO3)3
Explanation
K3[Fe(CN)6]dissociates into 3K+ ions and one [Fe(CN)6]3- ion. So its Van't Hoff factor is 4. Al(NO3)3 dissocaites into one Al3+ and three NO3- ions

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
