Colligative Properties Defined

The idea
A colligative property of a solution depends on the number of dissolved solute particles present, not on their chemical identity.
In practice
Equal-concentration solutions of sucrose and ethylene glycol produce the same boiling-point elevation, since both add the same particle count.
Where people slip
"Colligative" means particle count is what matters — swapping one nonelectrolyte solute for another of equal molality changes nothing.
