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..
The solubility of ionic salts in water is generally determined by the degree of solvation of the ions by water molecules. Such coordination complexes occur by water donating spare electrons on the oxygen atom to the ion.aking a saline water solution by dissolving table salt (NaCl) in water. The salt is the solute and the water the solvent. Gold, formerly dissolved in crystal of pyrite, is left behind after the cubic crystal of pyrite dissolved away. Note a corner of the former cube seen in center of rock.
