Generally "like dissolves like". Water is a polar molecule and so will tend to dissolve anything polar (i.e. with some kind of charge) and not dissolve non-polar substances. Examples of things that do dissolve are many ionic substances (though not all) and shorter chain alcohols such as ethanol. Longer chains don't dissolve as well as they get more non-polar in character.
