Pressure does not play much of a role in the solubility of a solid into a
liquid, but it does play a big role in the solubility of a gas. For instance,
soda is a carbonated drink, and it contains CO2 (that is why it
bubbles). There is a mathematical representation between pressure and
concentration. It is called Henry's Law, and it states that the partial pressure
of the gas (P) is directly proportional to the concentration of the solution (C)
or in terms of the variables ...
P = k Cwhere k is the constant for that
