Chemistry Question on Colligative Properties

Which of the following solutions will have the highest boiling point?

A

0.1 M FeCl30.1\, M\,FeCl _{3}

B

0.1 M BaCl20.1\, M\,BaCl _{2}

C

0.1 M NaCl0.1\, M\, NaCl

D

0.1 M0.1\, M urea

Answer

0.1 M FeCl30.1\, M\,FeCl _{3}

Explanation

Solution

0.1 M FeCl30.1\, M\,FeCl _{3} will give the maximum number of particles ( iei e, ions) in the solution. Hence, its elevation in boiling point is maximum and therefore, it has highest boiling point. FeCl3Fe3++3Cl−FeCl _{3} Fe ^{3+}+3 Cl ^{-}
