What is the unit of Henry's law constant?
What is the unit of Henry's law constant?
Solution and Explanation
The unit of Henry's law constant (kH) depends on the units of the partial pressure of the gas and the concentration of the gas in the liquid phase. If the partial pressure of the gas is in atmospheres (atm) and the concentration of the gas in the liquid phase is in moles per liter (M), then the units of kH are: L·atm/mol If the partial pressure of the gas is in pascals (Pa) and the concentration of the gas in the liquid phase is in moles per cubic meter (mol/m³), then the units of kH are: m³·Pa/mol

Solutions
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
Types of Solutions:
The solutions can be classified into three types:
- Solid Solutions - In these solutions, the solvent is in a Solid-state.
- Liquid Solutions- In these solutions, the solvent is in a Liquid state.
- Gaseous Solutions - In these solutions, the solvent is in a Gaseous state.
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
- Unsaturated Solution- A solution in which more solute can be dissolved without raising the temperature of the solution is known as an unsaturated solution.
- Saturated Solution- A solution in which no solute can be dissolved after reaching a certain amount of temperature is known as an unsaturated saturated solution.
- Supersaturated Solution- A solution that contains more solute than the maximum amount at a certain temperature is known as a supersaturated solution.
