Web sodium and chlorine presumably react together strongly, which is why the solid product is stable and takes a lot of energy to break the bonds formed, and to melt. After that is done, the water molecules surround the ions and form hydration spheres. When cacl2 dissolves in water, heat is released. Calcium chloride is an inorganic compound, a salt with the chemical formula cacl2. Molten calcium chloride can be electrolysed to give calcium metal and chlorine gas: Web an infinitely dilute solution is one where there is a sufficiently large excess of water that adding any more does not cause any further heat to be absorbed or evolved. So why is n a c l so very soluble in water, and when it does dissolve and precipitate, very little heat appears to be involved? What does cacl2 look like when dissolved in water? At atmospheric pressure, dry ice. Give the term for the temperature at which the gas and liquid phases form a supercritical fluid.
