Here's a breakdown:
* Solubility: The amount of gas that can dissolve in a liquid at a given temperature and pressure.
* Partial Pressure: The pressure exerted by a specific gas in a mixture of gases.
* Directly Proportional: This means that as the partial pressure of the gas increases, the solubility of the gas in the liquid also increases proportionally.
In simpler terms:
Think of a can of soda. When you open it, the pressure inside is released, causing the dissolved carbon dioxide (CO2) to escape as bubbles. This happens because the partial pressure of CO2 above the liquid decreases, which in turn reduces its solubility in the soda.
Key Points:
* Henry's Law only applies to gases dissolved in liquids.
* The temperature is held constant in this law.
* The proportionality constant (Henry's Law constant) depends on the specific gas and the liquid.
Example:
If you increase the partial pressure of oxygen above a body of water, more oxygen will dissolve in the water. This is why fish can survive in deeper water where the pressure is higher.
