"WebAug 15, 2024 · Reactions with Water. Usually, reactions of chlorine with water are for disinfection purposes. Chlorine is only slightly soluble in water, with its maximum solubility occurring at 49° F. After that, its solubility decreases until 212° F. At temperatures below that range, it forms crystalline hydrates (usually \(Cl_2\)) and becomes insoluble. " - Solubility of helium in water
