0.01 M solution each of urea, common salt and Na₂SO₄ are taken, the ratio of depression of freezing point is
A.1: 1: 1
B.1: 2: 1
C.1: 2: 3✓ Correct
D.2: 2: 3
Explanation
f f T iK m since the concentration is same, so depression on value of i Van’t Hoff factors Urea=1 common salt = 2 sodium sulfate = 3 2 4 : : 1: 2 : 3 Urea NaCl Na SO
