Question

Determine the boiling point of 1m solution of sugar glucose urea sodium chloride aluminium chloride praticall

Answer 1

It is supposed the solvent is water and its pressure is constant.  Normal boiling point at 1 atm is 100°C.  

According to Raoult's law:    

ΔT b = K b x i x b (solute)

For  Sugar, Glucose and Urea :   i = 1,  ΔTb = 0.512 degree C   T b = 100.512 degree C

For   sodium chloride :  i = 2  (or 1.9) :  ΔT b = 1.024 degree C,   T b = 101.512  degree C

For  barium chloride :  i = 3 :      T b = 101.536 degree C

For   aluminium chloride   :  i = 4         T b = 102.048 degree C

where  i = No. of solute particles in solution ( total dissociated ion per molecule )
