Selection of stainless steels for handling chlorine (Cl2) …
Chlorine in contact with water and as a dissolved gas, sometimes found in water treatment appliions, is potentially aggressive to stainless steels. Localised crevice & pitting corrosion attack is a hazard in water and stress corrosion cracking (SCC) can be an additional hazard in damp chlorine gas, if the temperature is high enough.
CDC | Facts About Chlorine
Chlorine gas is heavier than air, so it would settle in low-lying areas. How chlorine works The extent of poisoning caused by chlorine depends on the amount of chlorine a person is exposed to, how the person was exposed, and the length of time of the exposure.
The Fundamentals of Chlorine Chemistry and Disinfection
Chlorine gas rapidly hydrolyzes to hypochlorous acid: Cl 2 + H 2O ÎHOCl + H+ + Cl– Aqueous solutions of sodium or calcium hypochlorite hydrolyze : Ca(OCl) 2 + 2H 2O ÎCa2+ + 2HOCl + 2OH– NaOCl + H 2O ÎNa+ + HOCl + OH– The two chemical species

Chlorine | Sutro Connect
Cl is a reactive non-metal and is a yellow-green halogen gas at room temperature. It has a strong oxidizing potential, which is why it is so effective as a disinfectant. Cl acts by attacking cell walls and destroying the enzymes and structures inside the cells of germs, which in turn kills the nasty microorganisms that can ruin your pool (or spa) experience.

Chlorine - Production and use | Britannica
17/8/2020· Chlorine - Chlorine - Production and use: Rock salt deposits are usually mined; occasionally water is pumped down, and brine, containing about 25 percent sodium chloride, is brought to the surface. When the brine is evaporated, impurities separate first and can be removed. In warm climates salt is obtained by evaporation of shallow seawater by the Sun, producing bay salt. Chlorine is produced
Swimming Pool Water Chemistry - Balanced Water
Chlorine in outdoor pools must be shielded from the degrading effects of the sun’s ultraviolet (UV) rays. Cyanuric acid is used in outdoor pools with the inorganic chlorines such as calcium hypochlorite, sodium hypochlorite, lithium hypochlorite and chlorine gas.
