Chloroform explodes when in contact with aluminum powder or magnesium powder or with alkali metals (eg, lithium, sodium, and potassium) and dinitrogen tetroxide it reacts vigorously with acetone in the presence of potassium hydroxide or calcium hydroxide. Chloroform is a dangerous chemical that irritates the eyes, respiratory system, and skin it can damage the nervous system , eyes, lungs, skin, liver, kidneys, and other organs and may cause cancer the chemical is readily absorbed into the body through the intact skin or from inhalation or ingestion. Chloroform, also referred to as trichloromethane is an organic compound each molecule of trichloromethane consists of three chlorine atoms attached to one carbon atom organic compounds having two or more than two halogen atoms attached to it are generally called polyhalogenated compounds.
A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols and numbers.

Chloroform trichloromethane, or chloroform, is a chemical compound with the formula chcl 3 it is one of many examples of a haloalkane, and is often used as a nonpolar solvent in organic chemistry.
Thus, diethyl ether and ethyl acetate, which are both less dense than the dilute solutions that are usually used for extraction, form the top layer, while dichloromethane and chloroform form the bottom layer (currently both of them are not used in chem 30bl or chem30cl due to safety concerns. Bromoform (chbr 3) is a brominated organic solvent, colorless liquid at room temperature, with a high refractive index, very high density, and sweet odor is similar to that of chloroform it is a trihalomethane , and is one of the four haloforms , the others being fluoroform , chloroform , and iodoform. Reaction with chloroform in the alkaline medium dissolve 01 g in 1 ml of water r, add 1 ml of strong sodium hydroxide solution r and 01 ml of chloroform r, heat and allow to cool an intense, deep-red colour develops which becomes pale yellow on the addition of a slight excess of hydrochloric acid r. Although chloroform is non-poisonous, if forms a poisonous compound (phosgene) in air chloroform is stored in a dark brown bottle with a tight lid so as to prevent the formation of poisonous phosgene.

Inhaled chloroform anesthesia was introduced in 1847 soon thereafter, the chemical reactivity of aerobically heated chloroform permitted john snow and claude bernard to do seminal experiments in the assay of drug levels and drug metabolism. Chloroform is the common name of the organic compound whose chemical formula is hccl 3 the molecule of trichloromethane, as it is also called, consists of a central carbon atom bonded to a hydrogen atom and three chlorine atoms. Structure, properties, spectra, suppliers and links for: chloroform, trichloromethane, 67-66-3, chcl3.
Prepared in the context of cooperation between the international programme on chemical safety & the commission of the european communities (c) ipcs cec 1994 no modifications to the international version have been made except to add the osha pels, niosh rels and niosh idlh values. Deuterated chloroform is an isotopologue of chloroform with a single deuterium atom cdcl 3 is a common solvent used in nmr spectroscopydeuterochloroform is produced by the haloform reaction,  the reaction of acetone (or ethanol) with sodium hypochlorite or calcium hypochlorite the haloform process is now obsolete for the production of ordinary chloroform.

Chloroform is a trichlorinated organic substance with the chemical formula of chcl 3 [19,266,267] it is a clear liquid at room temperature and has a pleasant, sweet odor it is a clear liquid at room temperature and has a pleasant, sweet odor. What’s wrong with chloroform chloroform is a iupac name the preferred name is trichloromethane many chemists will feel the sudden urge to soak some chloroform in a rag and make the person unconscious if someone dares to ask for the bottle of trichloromethane.
In this video we make chloroform from bleach and acetone the yield is a little lower than expected because i used an 11% excess of acetone, which is too much. Chloroform needs to be stored in a cool, dry, well-ventilated place, out of direct light your choice of storage container is likely to be influenced by how long you intend to store it for, but an amber glass bottle with a ptfe-lined cap is probably best suited for longer storage. However, academic discussions on pharmaceutical chemistry and the science of explosives are permitted no memes, rage comics, image macros, reaction gifs, or other zero-content material ever disposal of chloroform (selfchemistry) submitted 4 years ago by mdogm.
