Polarity determines if a substance is water-soluble. A polair substance is a substance that has two kinds of 'poles', as in a magnet. When another substance is also polair the poles of the substances attract each other and as a result the substances mix. A substance then dissolves in water.
Substances that contain no 'poles' are called apolair substances. Oil for instance is an apolair substance, which is why oil does not dissolve in water. In fact it floats on water, just like ice, due to its smaller density..

Water - solubility is the availability of the required bond energy from the loosely packed water molecules to break the interatomic bonds of the substance that is intended to be dissolved in water. Insolubility of certain substances is the unavailability of sufficient bond energy from water molecules to form hydrogen bonds with the molecules of the substance.

a substance needs to have an ionic bond in order to dissossciate to be soluble in water.

good answer eubzz.
now here's my answer.
'cause if every substance were water soluable then single celled organisms wouldn't have ever lived in the primordial ooze billions of years ago and you wouldn't be here to ask the question.
so basically what i'm sayin' is this...
not everything is water soluable 'cause that would just be pointless.

It all depends on the surface tension of the substance.

polarity differs .the polarities of all the compounds which r greater than water will not dissolve in water.

Because of its smaller density

Most are at least in trace form.
