WebChloroform is a colorless, volatile liquid that is nonflammable. It is slightly soluble in water and is miscible with oils, ethanol, ether, and other organic solvents. Chloroform has a pleasant, nonirritating odor. It is unstable when exposed to air, light, and/or heat, which cause it to break down to phosgene, hydrochloric acid, and chlorine. Web2 days ago · This is because chloroform reacts with oxygen to form a highly poisonous gas known as phosgene when exposed to light. Chloroform gets slowly oxidized by the air in the presence of ultraviolet rays from the sun and leads to the formation of a highly poisonous gas known as phosgene.
