What gas does chlorine belong to?

Chlorine gas, chemical formula Cl? . It is yellow-green at normal temperature and pressure, and it is a highly toxic gas with strong pungent smell. Chlorine has the following characteristics:

1, physical properties: chlorine is a yellow-green gas with pungent smell. It is slightly heavier than air. At room temperature, chlorine is relatively stable and not easy to burn.

2. Chemical properties: chlorine has high electronegativity and is a strong oxidant. It can react with many substances, such as metal to produce corresponding metal chloride and hydrogen to produce hydrochloric acid. Chlorine can also participate in the chlorination reaction of organic compounds and be used to synthesize various organic chlorides.

3. Toxicity: Chlorine has certain toxicity. High concentration of chlorine will irritate human respiratory tract and eyes, and in severe cases, it will lead to suffocation and tissue damage. Therefore, it is necessary to take necessary safety measures when using chlorine to ensure proper ventilation and use protective equipment.

Matters needing attention in using chlorine gas

1. Protective equipment: When handling chlorine gas or contacting chlorine gas environment, you must wear appropriate protective equipment, including protective glasses, protective masks, chemical protective gloves and protective clothing. These devices can reduce direct contact with chlorine and protect respiratory tract, skin and eyes.

2. Ventilation: When using chlorine gas, ensure good ventilation conditions and try to operate outdoors with good ventilation or with the assistance of ventilation equipment. Avoid long-term contact with chlorine gas in a closed space to prevent the gas concentration from accumulating too high.

3. Precautions for operation: When operating chlorine, avoid chlorine leakage or overflow. Try to use sealed containers to store and transport chlorine to reduce the possibility of leakage. Handle with care to avoid violent shaking or collision with the container.

4. Emergency response: After accidental leakage or leakage, leave the leakage area immediately and look for a safe place. Inform relevant personnel in time and start emergency handling procedures. Avoid inhaling leaked chlorine directly and find a place to breathe fresh air.

5. Precautions for storage: If chlorine gas needs to be stored for a long time, it should be stored in a cool, dry and well-ventilated area, away from fire sources and flammable materials. Storage containers must meet relevant safety standards and ensure good sealing performance.
