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..
Sodium Chloride is common table salt, but there are many many many other types of salt. Each salt has its own solubility in water, some salts are very soluble, some salt not so much, some salts are totally insoluble in water, it all just depends on the salt. Solubility rules have been developed to help determine whether a particular salt will be soluble or not dependin on the salts cation or anion.
