Chapter 13, Problem 141AP

Interpretation Introduction

Interpretation:

The concentration of the aqueous solution in the body of the tree that would remain unfrozen at the given temperature and the estimated concentration is reasonable or not are to be determined and a comment is to be made on the result.

Concept Introduction:

The property that depends on the concentration of solute molecules and not on the identity of solute is termed as colligative property.

The four colligative properties of solution are vapor-pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.

The depression in freezing point by the addition of a solute in a pure substance is calculated as

$\Delta T_f=K_f.m$

Here, $\Delta T_f$ is the depression in freezing point, $K_f$ is the freezing point constant, and $m$ is the molality.
