Definition: The molar mixing ratio in aqueous phase is the abundance of one component of a mixture relative to that of all other components in the aqueous solution.
Purpose: This calculation is essential in atmospheric chemistry, environmental science, and chemical engineering to understand gas-liquid partitioning.
The calculator uses Henry's Law formula:
Where:
Explanation: The molar mixing ratio is directly proportional to both the Henry solubility constant and the partial pressure of the species.
Details: Accurate calculation helps predict how gases will partition between the atmosphere and aqueous solutions, important for environmental modeling and industrial processes.
Tips: Enter the Henry solubility constant (Hxp) in Pa-1 and the partial pressure (Pspecies) in Pascals. All values must be > 0.
Q1: What is Henry's Law?
A: Henry's Law states that the amount of dissolved gas is proportional to its partial pressure above the solution.
Q2: Where can I find Henry solubility constants?
A: These are typically found in chemical engineering reference tables or atmospheric chemistry databases.
Q3: What units should I use?
A: The calculator uses SI units - Pascals for pressure and reciprocal Pascals for Henry's constant.
Q4: Can this be used for any gas?
A: Yes, as long as you have the correct Henry solubility constant for that specific gas.
Q5: How does temperature affect the results?
A: Henry's constant is temperature-dependent, so ensure you're using the correct value for your temperature conditions.
