Chapter 12, Problem 43RQ

Interpretation Introduction

Interpretation:

In the aqueous solution 0.50m NaI or 0.50 m ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$, which of these would have the higher boiling point, is to be determined.

Concept Introduction:

The boiling point is defined as the temperature at which any solution starts to boil. The boiling point elevation is given by the following equation:

$\Delta T_b=T_b{}_{observed}-T_b{}_{pure }$.

In the above-mentioned equation, $\Delta T_b$ refers to boiling point elevation, $T_b{}_{observed}$ refers to elevation in the boiling point after the addition of a certain substance, and $T_b{}_{pure }$ refers to the boiling point of water.
