Chapter 12, Problem 12.77QP

Interpretation Introduction

Interpretation: For ${\text{CaCl}}_{\text{2}}$ solution Van’t Hoff factor to be calculated.

Concept introduction

Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution. We can calculate osmotic pressure by using this formula is given by,

Osmotic pressure $\text{(π) = iMRT}$

Where,

i- Von’t Hoff’s factor

M – Molarity of the solution (mol/L)

R- Ideal gas constant (0.08206${\text{L atm mol}}^{\text{-1}}{\text{K}}^{\text{-1}}$)

T-Temperature in Kelvin
