Chapter 5, Problem 5F.10E

Interpretation Introduction

Interpretation:

Among the given solutions, the solution that has the highest osmotic pressure at ${\text{50}}^{\text{°}}\text{C}$ has to be identified.

  (a) $\text{0}\text{.10}\text{M}{\text{KCl}}_{\text{(aq)}}$

  (b) $\text{0}\text{.60}\text{M}\text{CO}{\left({\text{NH}}_{\text{2}}\right)}_{\text{2}\left(\text{aq}\right)}$

  (c) $\text{0}\text{.30}\text{M}{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}\left(\text{aq}\right)}$.

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:

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