Chapter 7, Problem 7.74E

Interpretation Introduction

Interpretation:

The explanation corresponding to the statement that the limp vegetables like celery can be crisped by soaking in cold water is to be explained. Also, the reason as to why salt water is not used is to be stated.

Concept introduction:

The osmotic pressure is generated in the case when there is osmosis of solvent molecules through a semi permeable membrane to a high concentration of solute molecules.

It is given by the formula given below

$\Pi \overline{V}=x_{\text{solute}}RT$

In the above expression, $\Pi$ is the osmotic pressure, $\overline{V}$ is the volume, $x_{\text{solute}}$ is the mole fraction, $T$ is temperature and $R$ is the gas constant.
