Chapter 13, Problem 13.55QP

Interpretation Introduction

Interpretation: For most intravenous injections, excessive care is taken to protect that the concentration of the solution to be injected compared to blood plasma has to be explained.

Concept introduction

Osmosis is the process by which net movement of solvent into a expanse of higher solute concentration via semi permeable membrane.

Semi permeable membrane which allows solvent molecules to overtake not allows solute molecule.

Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution. We can calculate osmotic pressure by using this formula is given by,

Osmotic pressure $\text{(π) = iMRT}$

Where,

i- Von’t Hoff’s factor

M – Molarity of the solution (mol/L)

R- Ideal gas constant (0.08206 ${\text{L atm mol}}^{\text{-1}}{\text{K}}^{\text{-1}}$)

T-Temperature in Kelvin
