Formation of Poisonous Compound from Chloroform
Chloroform (CHCl3) is a volatile, colorless liquid with a sweet-smelling odor. When exposed to light and air, chloroform undergoes oxidation to form phosgene (COCl2), which is a poisonous compound. This reaction occurs due to the presence of oxygen in the air, which facilitates the oxidation process.
Reason for Storing Chloroform in Dark Colored Bottles
Chloroform is stored in dark colored bottles to prevent its exposure to light. Light can trigger the oxidation of chloroform, leading to the formation of phosgene. By storing chloroform in dark bottles, the chances of oxidation are minimized, thereby reducing the risk of producing the poisonous compound.
Importance of Preventing Phosgene Formation
Phosgene is a highly toxic and corrosive gas that can cause severe respiratory issues, irritation, and even death upon inhalation. Therefore, it is crucial to prevent the formation of phosgene by storing chloroform appropriately in dark colored bottles away from light sources.
In conclusion, the oxidation of chloroform in the presence of light and air can lead to the formation of phosgene, a poisonous compound. By storing chloroform in dark colored bottles, the risk of oxidation and phosgene formation is minimized, ensuring safe handling and storage of the chemical.
