Question

what are the expression of Henry's law????

Answer 1

Henry's law defines that at constant temperature, the concentration of the gas that is dissolved in a given liquid is proportional to the partial pressure of the gas above the fluid. The Henry's law constant is the expression for equilibrium distribution of a compound between water and gaseous phase denoted by KH.

Answer 2

The mathematical expression for Henry’s law is given by

$k = \frac{p}{c}$


Where,

c is the solubility of the gas at a fixed temperature in a solvent (units in M or ml gas/L).

k is the Henry’s law constant (units in M/atm)

p is the partial pressure of the gas (units in Atm )
