what gas does not desolve in water?

Question

name a gas that is not water soluble,
how do you make that gas, if possible can it be a gas that is produced using an acid.

Answer 1

There aren't strictly speaking any gases that are 100% insoluble. Gases that dissolve well are those that can react with water, typically forming acids, eg SO2 or CO2, dissolve to form sulphuric and carbonic acid respectively. Chemically (relatively) unreactive gases are not very soluble, and of these, the lighter (ie, more volatile) the substance, the less it will tend to dissolve. Therefore, good choices are hydrogen or helium. Helium is inert and thus is not the product of a chemical reaction. Hydrogen is produced by adding alkali metals to water.
If you really wanted to produce it using an acid, you could do so by reacting the acid with a metal hydride, MH, producing a salt and hydrogen gas. From a practical point of view, the reaction of metal hydrides with acids tends to be rather violent.

Answer 2

Nitrogen, Helium

Basically any gas which is non polar.

Answer 3

methane, it's called marsh gas.
I think any inert gas will not dissolve much.
