Question

Define Osmosis and Osmotic pressure. How the molecular mass of a non volatile and non-electrolyte solute is determined with the

help of Osmotic pressure measurement?​

Answer 1

Answer:

Osmosis and Osmotic Pressure

You have studied the principle of osmosis. You have possibly done some experiments with salt water as well. Haven’t you seen pickles being made at home? That is all the magic of osmosis. But, how does osmosis work? Do you know that osmosis is one major reason for the survival of many species? In this chapter, we will study all about osmosis and osmotic pressure.

DEAR FRIEND I HOPE THIS ANSWER WILL HELP YOU

OSMOSIS-when we separate a dilute solution from a concentrated solution of the same type by a membrane, the solvent molecules flow from the dilute solution to the concentrated solutions. This movement continues until it reaches an equilibrium. This process of flow of solvent molecules due to the difference in concentration is osmosis.

OSMOTIC-Osmotic pressure is the pressure that we need to apply to stop the flow of solvent molecules from a dilute solution to a concentrated solution through a semi-permeable membrane.

- Cryoscopic method is one of the best method used to determine the molecular mass of a non-volatile solute

we have,

ΔT f =K  f m

where, ΔT  f  is calculated experimentally and K   f  is constant and by using molality we can easily find the molecular weight of solute particle.

HOPE THIS HELPS YOU.
