Interpretation Introduction

Interpretation:

The solution that is isotonic with the solution represented by the diagram A should be identified.

Concept introduction:

All the membranes found in living systems are semi-permeable in the sense that they allow only selective entry and exit of small molecules and restrict the movement of large particles.

The phenomenon of osmosis may be defined as the process that allows the movement of solvent from the region of high solvent concentration to region of low solvent concentration. The colligative property associated with osmosis is termed as osmotic pressure which may be defined as the least amount of pressure that must be exerted on the solution side so as to prevent the flow of pure solvent across the membrane.

All colligative properties are dependent upon the concentration of particles irrespective of the nature of the particles.
