Which aqueous sol has lowest freezing point a)0.1m sucrose b)0.1m glucose c)0.1m nacl d)0.1m bacl2
for d) BaCl2 -------> Ba2++2Cl- it gives 3 ions on dissociation so vant hoff factor(i) = 3 depression in freezing point depends unon i if molality is constant, so for BaCl2 it is max hence lowest freezing point..
