The Air Saturated in Water Calculator is designed to compute the concentration of gases like oxygen and nitrogen dissolved in water based on temperature and the partial pressure of these gases above the water. This calculation is critical for applications ranging from environmental science to engineering and health, providing a quantitative measure of gas concentration that influences aquatic life and water chemistry.
Formula of Air Saturated In Water Calculator
The calculation of gas concentration in water involves key concepts from Henry’s Law, which describes the solubility of gases in liquids:
- Determine the Partial Pressure of the Gas (P_gas):
- The partial pressure of the gas above the water, measured in atmospheres (atm) or any other consistent unit of pressure.
- Determine Henry’s Law Constant (k_H):
- This constant varies with the gas and temperature, typically given in units like mol/(L·atm).
- Calculate the Concentration of the Gas in Water (C_gas):
- The formula to determine the gas concentration in water is: C_gas = k_H * P_gas
- C_gas is the concentration of the gas in water, measured in moles per liter (mol/L).
- k_H is Henry’s Law constant for the gas at a specific temperature.
- P_gas is the partial pressure of the gas.

Example of Air Saturated In Water Calculator
Suppose you want to calculate the concentration of oxygen in water at a temperature where Henry’s Law constant for oxygen is 0.0013 mol/(L·atm) and the partial pressure of oxygen above the water is 0.21 atm. Using the provided formula:
- k_H = 0.0013 mol/(L·atm)
- P_gas = 0.21 atm
The concentration of oxygen in the water would be: C_gas = 0.0013 * 0.21 = 0.000273 mol/L
This calculation helps determine the dissolved oxygen available in water, which is crucial for aquatic life.
Most Common FAQs
Generally, the solubility of gases decreases as the temperature increases, due to the increased kinetic energy allowing gas molecules to escape more easily.
It is vital for assessing the health of aquatic environments, the operational efficiency of industrial processes, and ensuring the safety of drinking water.
Yes, the calculator can be used for any gas as long as the appropriate Henry’s Law constant and partial pressure are known.
