The gas should contain polar molecules. The water should be at a low temperature, and the gas should be at high pressure above the surface of the water.

Explanation:

Water is a dipolar molecule due to presence of electronegative oxygen atom as well as angular structure of water molecule.

So water attracts polar molecules through dipole-dipole attraction force and hence polar molecules get dissolved into water.

Water should have low temperature during dissolution of gas into water. Because, at high temperature, intermolecular force between gas and water molecule tend to break apart.

At high pressure, gas molecules are forced to enter into bulk liquid. Thus dissolution of gas into liquid becomes favorable.

Answer from: traphard979

Explanation:

It is known that water is a polar molecule due to the difference in electronegativity of hydrogen and oxygen atom there is a positive partial charge on hydrogen and a negative partial charge on the oxygen atom.

So, being a polar molecule water readily dissolve substance which are also polar in nature.

Hence, for a gas to be soluble in water it is required that the gas should contain polar molecules.

Also, water should be at low temperature because otherwise gas will evaporate from the solution due more gain in kinetic energy.

As, Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, as follows.

$p_{i} = K_H\times p_{liquid}$

where, K_H = Henry's constant = $3.7\times 10^{-2}mol/L.atm$

$p_{i}$ = partial pressure a gas

Therefore, pressure of the gas should be high at the surface of water.

Thus, we can conclude that for a gas to be soluble in water, the gas should contain polar molecules. The water should be at a low temperature, and the gas should be at high pressure above the surface of the water.
