Chapter 6.8, Problem 6.14QC

Interpretation Introduction

Interpretation:

The solution which is isotonic as compared to red blood cell should be selected.

Concept introduction:

The concepts which are used here are as follows:

• Colligative Properties: The property of ideal solution which depends only on the number of particles of the solute dissolved in a definite amount of solvent and does not depends on the nature of the solute.
• Osmolarity: It is defined as the number of moles of osmotic solute concentration per litre of solution.
• Isotonic solution: If two solutions have same osmotic pressure then it is called isotonic solution.
• Van’t Hoff factor: It is defined as the ratio of the experimental value of colligative property to the calculated value of the colligative property. Since osmosis is a colligative property so the relation between van’t hoff factor and osmolarity is

Where i is the van’t hoff factor and m is the molarity. $\text{O}sm\text{O}\text{l}\text{a}r\text{i}ty=\text{i}\times M$
