Which aqueous sol has lowest freezing point a)0.1m sucrose b)0.1m glucose c)0.1m nacl d)0.1m bacl2
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..
