Why is the solubility of one gas in another unlimited?

Answer 1

Because gases don't "dissolve", such as sugar into water; or become "micible" in a liquid. For example if your try and mix cooking oil with water they won't mix. This is because in each layer all of the water molceules are up against one another, and like wise with the oil molecules.

Now since gas molecules (or atoms) are not up against one another, but are seperated by a small distance. Since there is open space, another gas can occuply that space and does not need to "dissolve" into a gas.

When you reach a point where their is no space, the gas then turns into a liquid and then solubility will come into play. Under hihg pressure you may know that natural gas is sotred as a liquid (in the tank is under pressure), and when it leaves your stove it comes out as a gas.

Hope i didn't confuse you

Answer 2

Think of all that room between molecules that are moving very fast. Even in a container; you would have another form of matter before solubility of one gas into another was limited.

Answer 3

when one liquid is miscible in the other or one solid is soluble in a liquid the solvent and solute must have similar nature of bonds (that is their polarity should match). there are intermolecular interactions between the solute and the solvent. polar solutes are soluble in polar solvents only and non-polar in non polar, so this is the one factor which limits the solubility of solutes in liquids while this is not a limiting factor in case of gases as most of them have very week intermolecular forces.
secondly since gaseous molecules are not very near to each other as is the case with liquid solvent.there is lots of space between the molecules and this counts for infinite solubility of gases in each other.

Answer 4

1) Gases have lots of space between the individual molecules. This leads to an almost infinitely elastic nature - they can be incredibly compressed & almost infinitely spread out.

2) Gases do not possess the properties which keep liquids apart; for instance, polarity/nonpolarity, or at least not sufficiently to overcome item #1.
