Of the following 0.10 m aqueous solution, which one will exhibit the largest freezing point depression?
KCl
C6 H12 O6
Al2(SO4)3
K2SO4
ΔTf=i×Kf×m So, ΔTf∝i (van't Hoff factor) SaltiKCl2C6H12O61Al2(SO4)35K2SO43 Hence, i is maximum i.e., 5 for Al2(SO4)3
Which of the following 0.10m aqueous solutions will cause highest depression in freezing point?
