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..
While many salts do have higher solubilities in hot water compared to cold water, some salts actually have less solubility in hotter water. We can report the solubility of a chemical at various temperatures. For example, the solubility of KBr in water at 25 o C is 64 g/100 g water.
