1. What is Henry's Law?

Henry's Law states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid. The proportionality constant is known as Henry's constant.

2. How Does the Calculator Work?

The calculator uses Henry's Law equation:

Where:

• \( H \) — Henry's Constant (atm/M)
• \( P \) — Partial Pressure (atm)
• \( C \) — Concentration (M)

Explanation: The equation calculates the solubility constant of a gas in a liquid at a specific temperature.

3. Importance of Henry's Constant

Details: Henry's constant is crucial for understanding gas solubility, environmental chemistry, and various industrial processes including carbonation of beverages and gas exchange in biological systems.

4. Using the Calculator

Tips: Enter partial pressure in atm and concentration in molarity (M). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect Henry's constant?
A: Temperature is the primary factor - solubility decreases with increasing temperature for most gases.

Q2: How does Henry's law apply to real-world scenarios?
A: It explains carbonation in soft drinks, oxygen dissolution in blood, and gas exchange in aquatic environments.

Q3: Are there limitations to Henry's law?
A: It works best for dilute solutions and gases that do not react chemically with the solvent.

Q4: What are typical units for Henry's constant?
A: Common units include atm/M, Pa·m³/mol, or dimensionless values depending on the concentration units used.

Q5: How does pressure affect gas solubility?
A: According to Henry's law, solubility increases linearly with increasing partial pressure of the gas.
