Henry's law is a principle in physical chemistry that describes the solubility of a gas in a liquid. It states that the amount of gas dissolved in a liquid is directly proportional to the partial pressure of the gas above the liquid.
Mathematically, Henry's law can be expressed as:
C = k * P
where:
C is the concentration of the dissolved gas in the liquid (in units of mol/L or M),
k is the Henry's law constant, which is specific to the particular gas and liquid system (in units of mol/(L·atm) or M/atm), and
P is the partial pressure of the gas above the liquid (in units of atm).
The equation can also be rearranged to solve for the partial pressure of the gas (P):
P = C/k
This equation indicates that the solubility of a gas in a liquid decreases as its partial pressure increases, and vice versa.
