Which one of the following 0.10M0 . 10M aqueous solutions will exhibit the largest freezing point depression?

Options

  1. Aglycine
  2. Bhydrazine
  3. CKHSO4{KHSO}_{4}
  4. Dglucose

Correct answer

C. KHSO4{KHSO}_{4}

Step-by-step solution

ΔTf=ikfm{\Delta T}_{f} = {ik}_{f}m
As mm is same for all electrolyte so
ΔTf\alphaim{\Delta T}_{f}\alphaim
Greater the value of i greater is depression in freezing point
For KHSO4i=3{KHSO}_{4}i = 3
And for Glucose, Ethylele Glycol & glycerol i=1i = 1
