Question
b) How is the KH value related to the solubility of gases in the liquid?
Solution
The KH value, also known as Henry's Law constant, is directly related to the solubility of gases in a liquid. Henry's Law states that at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.
Here are the steps to understand this relationship:
-
When the KH value is high, the solubility of the gas in the liquid is low. This is because a high KH value means that the gas prefers to stay in the gas phase rather than dissolving in the liquid.
-
Conversely, when the KH value is low, the solubility of the gas in the liquid is high. A low KH value indicates that the gas prefers to dissolve in the liquid rather than staying in the gas phase.
-
The KH value is determined experimentally and is specific for each gas-liquid pair at a specific temperature.
-
The solubility of gases in liquids decreases with increasing temperature. This is because the KH value increases with increasing temperature.
-
Therefore, by knowing the KH value for a specific gas-liquid pair at a specific temperature, one can predict the solubility of the gas in the liquid.
