Question # The freezing point among the following equimolal aqueous solutions will be highest for

# The freezing point among the following equimolal aqueous solutions will be highest for

a. ( C_{6} mathrm{H}_{5} mathrm{NH}_{3} mathrm{Cl} ) (aniline hydrochloride)

b. ( mathrm{Ca}left(mathrm{NO}_{3}right)_{2} )

c. ( mathrm{La}left(mathrm{NO}_{3}right)_{3} )

( mathrm{d} . mathrm{C}_{6} mathrm{H}_{12} mathrm{O}_{6} ) (glucose)

Solution

( C_{6} H_{12} O_{6} ) (glucose)

Glucose being nonelectrolyte produces

lesser value of ( -Delta T_{f} ) and hence higher

freezing point.
