Kloorikaasulla

Kloorikaasulla, also known as chlorine gas, is a chemical compound with the formula Cl₂. It is a diatomic molecule composed of two chlorine atoms covalently bonded. Under standard conditions, chlorine gas is a yellow-green, pungent gas. It is denser than air and has a distinct, irritating odor.

Chlorine gas is highly reactive and a strong oxidizing agent. It is toxic and corrosive, posing significant health risks upon inhalation. Exposure can cause respiratory irritation, coughing, chest pain, and in severe cases, pulmonary edema and death. It is also an irritant to the eyes and skin.

Historically, chlorine gas was developed as a chemical weapon and used during World War I. Its use in warfare has since been banned by international conventions. In industrial applications, chlorine gas is a vital chemical intermediate. It is widely used in the production of plastics, solvents, pesticides, pharmaceuticals, and disinfectants, including for water purification. Due to its hazardous nature, the production, storage, and transport of chlorine gas are subject to strict safety regulations. Safety measures include ventilation, personal protective equipment, and emergency response plans.
