1. What is Dimensionless Henry Solubility?

Definition: Dimensionless Henry Solubility is the ratio between the aqueous-phase concentration of a species and its gas-phase concentration.

Purpose: It helps in understanding the partitioning of a chemical species between aqueous and gaseous phases.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ H_{cc} = \frac{c_a}{c_g} \]

Where:

Explanation: The aqueous phase concentration is divided by the gaseous phase concentration to get the dimensionless Henry solubility constant.

3. Importance of Henry Solubility

Details: This parameter is crucial in environmental chemistry, chemical engineering, and atmospheric sciences for predicting how chemicals distribute between air and water.

4. Using the Calculator

Tips: Enter the concentrations in aqueous and gaseous phases in mol/m³. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What does a high Henry Solubility value indicate?
A: A high value indicates the species prefers the aqueous phase over the gaseous phase.

Q2: What are typical units for Henry's Law constants?
A: While this calculator gives a dimensionless value, Henry's Law constants can also be expressed in atm·m³/mol or other units.

Q3: How does temperature affect Henry Solubility?
A: Generally, solubility decreases with increasing temperature for gases.

Q4: What's a typical value for common gases?
A: For CO₂ at 25°C, it's about 0.83; for O₂, about 0.03 (dimensionless).

Q5: Can this be used for volatile organic compounds?
A: Yes, the same principle applies to any species that exists in both phases.
