Chapter 13, Problem 83QP

Interpretation Introduction

Interpretation:

The use of osmotic pressure to determine the percent ionization of a weak, monoprotic acid is to be explained.

Concept introduction:

Osmotic pressure is the minimum pressure that has to be applied to prevent the flow of solvent into the solution, through the semipermeable membrane.

The relation between molarity and osmotic pressure is expressed as follows:

$\pi =M\text{R}T$

Here, $\pi$ is the osmotic pressure, R is the solution constant, $T$ is the temperature, and $M$ is themolarity of the solution.

Weak acids are the acids that ionize feebly.
