Question

The solubility of gases depends upon some factors.

1. Can you suggest the factors? 

2. Which is the law behind it? 

3. What are the limitations of this law?

Answer 1

1. Nature of the gas, Nature of the solvent, Pressure, Temperature.

2. Henry’s law. It states that the mass of a gas dissolved per unit volume of the solvent at a given temperature is proportional to the pressure applied on it.

3. Henry’s law is valid only under the following conditions :

• The pressure of the gas is not too high. 
• The temperature is not too low. 
• The gas is not highly soluble.
