The fact that water is a universal solvent is a commonly used sentence, but it does not mean that no substance is insoluble in water. fats for example are practically insoluble in water, as the experiment of putting oil in water simply demonstrates (the two phases remains separated).

Water is very good at solving polar substances due to the polar nature of the water molecule that is able to establish weak bond with a very low energetic content (called hydrogen bonds) with charged molecules .

When a polar solute is put in water, the solute molecules are decomposed by water in charged parts (called ions) that are surrounded by a layer of water molecules bonded to ions with hydrogen bonds. This configuration has a lower energy content with respect to the configuration of water alone and solute molecules alone, thus the solute molecule decomposition is spontaneous.

Water is a universal solvent because it possess the character in which it supports breaking and making of many kinds of bonds which help a substance to dissolve in water ,only few bonds are not capable of breaking in water. And other than compounds ,even few metals dissolve or disintegrate slowly in water by making or breaking bonds with it or help to form bonds with other substance.
