Chapter 13, Problem 13.83SP

Interpretation Introduction

Interpretation:

TheHenry’s law constants and solubility of ${\text{H}}_{\text{2}}\text{S}$ at 0°C need to be determined if the partial pressure is 25.5 mmHg and the solubility of ${\text{H}}_{\text{2}}\text{S}$ in water at STP is 0.195 M.

Concept introduction:

Henry's law is a gas law that states that the amount of dissolved gas in a liquid is proportional to its partial pressure and this proportionality factor is called Henry's law. The mathematical expression of Henry's law is:

${\text{Concentration = K}}_{\text{H}}\text{ × Partial pressure}$

Here concentration represents the solubility and K_H is the Henry’s constant.
