The solubility of nitrogen gas is $1.90 \mathrm{~mL} / \mathrm{dL}$ of blood at 1.00 atm. What is the solubility of nitrogen gas in a scuba diver's blood at a depth of 225 feet and a pressure of 8.00 atm?

Key Concepts

Henry's Law

Henry's Law states that the amount of gas that dissolves in a liquid is directly proportional to the partial pressure of the gas above the liquid. This fundamental principle of gas-liquid equilibrium is widely used to predict and understand the solubility of gases under varying pressure conditions.

Partial Pressure

Partial pressure refers to the individual pressure exerted by a gas within a mixture of gases. In the context of gas solubility, it is the pressure of the specific gas of interest that directly influences how much of it will dissolve in a liquid, according to Henry's Law.

Direct Proportionality Between Pressure and Solubility

The concept of direct proportionality in gas solubility indicates that if the pressure of a gas above a liquid is increased, the gas's solubility in the liquid increases correspondingly. This relationship is crucial for understanding changes in gas concentration in liquids under different pressure conditions, such as those encountered in high-pressure environments.

Gas-Liquid Equilibrium

Gas-liquid equilibrium describes the state in which the rate at which gas molecules dissolve in a liquid equals the rate at which they escape back into the gas phase. This equilibrium is foundational for applying principles like Henry's Law to determine the solubility of gases, ensuring accurate predictions in natural and engineered systems.
