## Henry's Law

Henry's Law (one of the Gas Laws), at a constant temperature, the volume of a gas which will dissolve into a solution is directly porportional to the partial pressure of that gas above the solution in equilibrium with the liquid.

### Henry's Law Constant Formila

$$\large{ k_H = \frac{ p_{gas} }{ c_{gas} } }$$

Where:

$$\large{ c_{gas} }$$ = the concentration of the solubility (gas) at a fixed temperature in a partial solution

$$\large{ k_H }$$ = Henry's law constant

$$\large{ p_{gas} }$$ = the partial pressure of the gas
