As we learned

 

Electrolytes -

Solute which  dissociates / associates when dissolved in solvent are known as Electrolytes

- wherein

e.g. NaCl2, CaCl2, KCl

 

 Elevation in boiling point is a colligative property which depends upon the number of solute particles. Greater the number of solute particle in a solution higher the extent of elevation in boiling point.

Na_{2}SO_{4}\rightarrow 2Na^{+}+SO_{4}^{2-}

 


Option 1)

0.015 M urea

Option 2)

0.01 M KNO3

Option 3)

 0.01 M Na2 SO4

Option 4)
