A. EXPERIMENTS TO BE PERFORMED
Aim:- To study the process of osmosis using potato osmoscope,
Requirements :- A fresh Potato, peeler or scalpel, Petri dishes/ bowls/ trough/ shallow glass
1. Study of osmosis by potato osmoscope.
Date :
beakers
, pins, concentrated sugar solution, coloured water, etc.
Principle
When two solutions of different concentrations are separated by semipermeable membrane,
the flow of solvent is from the region of weaker solution (having low solute concentration) to the
region of stronger solution (having high solute concentration) till the equilibrium is reached so
that the osmotic pressures are balanced.
Osmosis is of two types viz. endosmosis and exosmosis.
