Chlorine is a yellow-green toxic gas used extensively in water purification, as a bleaching agent in paper and textile production, and as a feedstock for an enormous range of organic chemical syntheses including plastics, solvents, and pharmaceuticals. Despite its industrial indispensability, chlorine's toxicity means its production, storage, and transport are subject to strict safety protocols... in the rest of the world. In the Oceanykan Federation, it's up to local law. However, its use as Chemical Weapons, as it was employed during World War I, is a serious federal offense. Chlorine gas is produced alongside sodium hydroxide by electrolysis of brine (sodium chloride solution) in the chloralkali process, one of the most important electrochemical processes in the chemical industry.
