1.	what is the significance of Henry's law constant KH
Answer» Henry's law is defined as, at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. Mathematically, at constant temperature: p = k_H c where p is the partial pressure of the solute in the gas above the solution c is the concentration of the solute and k_H is Henry's law constant, depends on the solute, solvent and the temperature. k_H : It has crucial importance in environmental chemistry, atmospheric chemistry, waste water treatment. They are needed since solubility affects volatilizations of toxic compounds into the air

Answer»

Henry's law is defined as, at a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.

Mathematically, at constant temperature:

p = k_H c

where p is the partial pressure of the solute in the gas above the solution

c is the concentration of the solute and

k_H is Henry's law constant, depends on the solute, solvent and the temperature.

k_H : It has crucial importance in environmental chemistry, atmospheric chemistry, waste water treatment.

They are needed since solubility affects volatilizations of toxic compounds into the air
