Chapter 5, Problem 5F.3BST

Interpretation Introduction

Interpretation:

The osmotic pressure of $\text{0}\text{.120}\text{M}$ sucrose solution at $\text{298}\text{K}$ has to be calculated.

Concept Introduction:

The pressure that is needed to stop the flow of solvent is known as Osmotic pressure.

The osmotic pressure of dilute solution is related to the molar concentration of the solute in the solution.  The osmotic pressure can be calculated by using the following equation:

  $\begin{array}{l}\text{Π}\text{=}\text{i}\text{R}\text{T}\text{c}\\ \text{where,}\\ \text{Π}\text{=}\text{Osmotic}\text{pressure}\\ \text{i}\text{=}\text{i}\text{factor}\\ \text{R}\text{=}\text{Gas}\text{constant}\\ \text{c}\text{=}\text{molar}\text{concentration}\\ \text{T}\text{=}\text{Temperature}\end{array}$
