Actually most of the salts are insoluble in water. Not all the salts include chloride!!! And of those witch contain chloride, silver, led and mercury salts are insoluble!!! chemically speaking, not all salts are soluble in a particular solvent under normal conditions..
In water, the positive end is composed of the hydrogen atoms and the negative end is the oxygen atom. When interacting with sodium chloride - common table salt - the positive sodium ion is drawn to the oxygen end of water and the negative chloride ion to the hydrogen end. Although common table salt easily dissolves in water, not all ionic salts do. If the strength of the attraction between the ions is much greater than the strength exerted by the slight charges of the water molecule, the ions remain bonded in water.
