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..
Some salt compounds are soluble in water and form aqueous ionic solutions. The most common salt solution is brine formed from sodium chloride solution in water. Other common ionic salt solutions contain salts of potassium, calcium, or magnesium.ydrated salts are salt compounds that include water molecules in their crystal structure. Many salts are found in hydrated form and maintain a solid crystalline state. The hydration of salt crystals is known as the water of crystallization, where water is often required for the crystal formation of the salt.
