Chapter 17, Problem 87E

Interpretation Introduction

Interpretation:

The minimum pressure that must be applied at 20 C to purify water that is 0.10 M NaCl by reverse osmosis needs to be deduced .

Concept Introduction:

Osmosis refers to the net flow of solvent molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration.

Osmotic pressure (p) is the difference in pressure across a concentration gradient. It is directly proportional to the molarity (M) of a solution.

π = iMRT -----(1)

Here,

R = gas constant and T = temperature

i = Von’t Hoff factor which is the number of ions per mole of solute dissolved in a given

solvent.
