What does “Colligative property” actually mean in Solutions & Colligative Properties, and why does it matter for NEET?
a property that depends only on the NUMBER of solute particles, not their identity — like freezing-point depression or osmotic pressure.
In simple words: a property that depends only on the NUMBER of solute particles, not their identity — like freezing-point depression or osmotic pressure. Getting Colligative property clear matters because NEET questions on Solutions & Colligative Properties usually test this idea directly, not just a formula you memorised.
Key point
Colligative property
Common mistake
thinking the kind of solute (sugar vs salt) matters more than how many particles it makes.
Memory tip
colligative = counts particles; 1 mole of NaCl ≈ 2 moles of particles.
