The sedative cloud ...Chloroform explodes when in contact with aluminum powder or magnesium powder or with alkali metals (e.g., lithium, sodium, and potassium) and dinitrogen tetroxide. It reacts vigorously with acetone in the presence of potassium hydroxide or calcium hydroxide. It is oxidized by strong oxidizers such as chromic acid forming phosgene and chlorine.Its use was eve- ntually abandoned, because of the dangerous side effects to one in 3,000 cases, (of paralysing the respiratory system and then heart of the inhaler). Chloroform belongs to a group of poisons which, when taken in large doses, corrodes and usually burns a consumers point of introduction, (i.e. nose or mouth).Chloroform (CHCl3) is dangerous due to its ability to depress the central nervous system. In fact, chloroform was once commonly used as an anesthetic for just these CNS depressing effects. A fatal oral dose can be a small as 10 mL.
