What is henry's law? Kaplan and Khan have different versions of the formula... which one is correct?

 

[Go_Pokes_11]

At a constant temperature, the amount of a gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.

At a constant temperature, the amount of a gas that dissolves in a liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.

Remember the assumption Henry's law makes, namely sufficiently dilute solution. Otherwise, Raoult's law applies.
