For which among the following equimolar aqueous solutions Van't Hoff factor has the lowest value?

Options

  1. AAluminium Chloride
  2. BPotassium Sulphate
  3. CAmmonium Chloride
  4. DUrea

Correct answer

D. Urea

Step-by-step solution

Urea is non-electrolyte and it's Van't hoff factor ( i ) is 1 . While other are electrolyte, So their ( i ) values are AlCl 3 = 4 K 2 SO 4 = 3 NH 4 Cl = 2
