ok ma'am
nice explanation mam
plz explain something for isc also
we are speachless mam you are great!!!!!!!!!!!
  1. Colligative Properties Properties depending on only number of solute particles

  2. There are four Colligative Properties Relative Lowering in Vapour Pressure Elevation in Boiling Point Depression in Freezing point Osmotic Pressure

  3. Relative Lowering in Vapour Pressure According to Raoult's law: Since 'B' is a non volatile solute no vapour pressure is contributed by Substracting both sides by 1, we have Or P The term Po-B-Lowering in vapour pressure -> This is not a colligative property The term Relative lowering in vapor pressure po-P This is a colligative property now nB WBXMA

  4. Elevation in boiling point Solvent Solution DT solvent solution Temperature

  5. W B m= WB

  6. Depression in Freezing point Tt Temperature/K

  7. Alf de m - kf m WB mMBXWA WB
