• Atomic number: 17
• Physical state: Greenish-yellow gas with a pungent odor
• Reactivity: Highly reactive and toxic
• Solubility: Moderately soluble in water, forming hydrochloric acid and hypochlorous acid

Common Uses of Chlorine

• Water treatment and disinfection: Chlorine is widely used to disinfect drinking water, swimming pools, and wastewater by killing bacteria, viruses, and other pathogens.
• Bleaching agent: Used in the production of paper, textiles, and household bleach.
