Because of non-reactive properties of the inert gases, these gases are useful to prevent the undesirable chemical reactions to happen.

They provide a non-explosive environment. They are also cheap and economical.

Food is packed in the inert gas to prevent rancidity. This also prevents bacteria from growing.  

The gases prevents the chemical oxidation by the oxygen in the normal air.

Triss [41]

Bromine and Iodine are both totally soluble in mineral oil because these substances are all made up of non-polar molecules. And because water is a polar molecule, Bromine and Iodine is not soluble in it.

Non polar solvents contain bonds that have similar electronegativity, an example of this is carbon and hydrogen such as gasoline. Some other examples are pentane, hexane, benzene and toluene.
