Chapter 18, Problem 44E

Interpretation Introduction

Interpretation:

The minimum pressure that must be applied by hand pumping at $297\text{K}$ to cause reverse osmosis to occur is to be calculated.

Concept introduction: Reverse osmosis is a water purification technique by which the ions, molecules and larger particles were removed from water by using semi permeable membrane. The osmotic pressure is defined as the pressure that must be applied to a solvent for its prevention from passing into a given solution by osmosis.

To determine: The minimum pressure that must be applied by hand pumping at $297\text{K}$ to cause reverse osmosis.
