# A water desalination plant is set up near a salt marsh containing water that is 0.10 M NaCl. Calculate the minimum pressure that must be applied at 20.°C to purify the water by reverse osmosis. Assume NaCl is completely dissociated.

Interpretation Introduction

Interpretation: The minimum pressure required to purify the water by osmosis process to be calculated.

Concept introduction

Desalination: Desalination is the action of removing salts that are dissolved in the water. Resulting, obtain pure water from seawater.

Osmosis: Osmosis is the process in which solvent molecule enter from low concentration into high concentration through semi permeable membrane.

Reverse osmosis: Reverse osmosis is water purification technique in which ions or molecule or larger molecules are removed by using semi permeable membrane.

Explanation

To calculate Van’t Hoff factor for given ionic solution.

i =mols of solutemols of ions

= 21 = 2.00

NaCl(aq) Na+(aq)+Cl-(aq)

The Van’t Hoff factor for ionic solution can be calculated by plugging the value of moles of the solute and moles of ion.

To calculate Van’t Hoff factor for given ionic solution.

i =mols of solutemols of ions

= 21 = 2
