what do you know about chlorides?

Question

i'm looking for information regarding their chemical structure, the different types of chlorides, their dangers and the damage they can potentially cause to the environment and humans.

Any information is much appreciated.

P.S. before people start telling me to do my own homework, i am doing my own research, just thought i might as well use this site as an untapped resource, theres people with all sorts of knowledge out there.

Answer 1

There are a very large number of chlorides but briefly many are salts. Practically every metal forms a chloride. As far as the environment is concerned it's not the chloride that's the problem but the metal it's combined with. (sea water contains a considerable amount of sodium chloride). Many of the other chlorides are organic and most of these are harmful to the environment. Common organic chlorides include dichloroethane which is used as a solvent and degreasing agent, tetrachlorimethane used in dry cleaning and polyvinyl chloride (PVC) with a multitude of uses as a plastic. The other noteable chloride is hydrochloric acid, which although corrosive is one of the least dangerous of the 'mineral acids.

Answer 2

Kind of a broad question. After all, table salt is sodium chloride, which in moderate amounts is actually necessary for life as we know it to exist -- you require it to maintain osmotic pressure in the cells of your body, and is used in various ways to promote cellular function (more the sodium ion than the chloride ion). Other substances, like carbon tetrachloride, is caustic and carcinogenic (but really useful as a dry-cleaning agent)

Generally speaking, when you speak of a chloride, you're usually talking about a salt or other substance that can liberate the chloride ion in solution. Any substance, even ones required for life, can be dangerous or even deadly in high enough concentrations. Salts in particular can wreak havoc on an ecosystem by drawing moisture and nutrients out of living cells into the surrounding water or soil, often killing those cells. Although there are species that thrive in high salt-content environments, they take a long time to evolve in a region like the Dead Sea or Great Salt Lake, so it's not like you'll suddenly get Sea Monkeys growing in your local pond if you dump a bunch of salts into it -- you'll just kill off all the plant and animal life in it until rainwater washes the excess salt away.

Chlorine has been used for many years and nothing g to blame . All kinds of compounds and they are good. Even HCh is not the danger that the environmentalist want u to believe. It is not that dreaded chemical. To neutralize it it is simple just use baking soda and at a ph if 7 it is harmless. That will make salt water ,just table salt. If it were not used in the purification of water many of us would be dead.

CHLORIDES: chemical compound containing chlorine. Most chlorides are salts that are formed either by direct union of chlorine with a metal or by reaction of hydrochloric acid (a water solution of hydrogen chloride) with a metal, a metal oxide, or an inorganic base. Chloride salts include sodium chloride (common salt), potassium chloride, calcium chloride, and ammonium chloride. Most chloride salts are readily soluble in water, but mercurous chloride (calomel) and silver chloride are insoluble, and lead chloride is only slightly soluble. Some chlorides, e.g., antimony chloride and bismuth chloride, decompose in water, forming oxychlorides. Many metal chlorides can be melted without decomposition; two exceptions are the chlorides of gold and platinum. Most metal chlorides conduct electricity when fused or dissolved in water and can be decomposed by electrolysis to chlorine gas and the metal. Chlorine forms compounds with the other halogens and with oxygen; when chlorine is the more electronegative element in the compound, the compound is called a chloride. Thus, compounds with bromine and iodine are bromine chloride, BrCl, and iodine chloride, ICI, but compounds with oxygen or fluorine (which are more electronegative than chlorine) are oxides (e.g., chlorine dioxide, ClO2) or fluorides (e.g., chlorine fluoride, ClF) respectively. Many organic compounds contain chlorine, as is indicated by common names such as carbon tetrachloride, methylene chloride, and methyl chloride. However, in the nomenclature system for organic chemistry adopted by the International Union of Pure and Applied Chemistry (IUPAC), the presence in a compound of chlorine bonded to a carbon atom is indicated by the prefix or infix chloro; thus, carbon tetrachloride is tetrachloromethane, methylene chloride is dichloromethane, and methyl chloride is chloromethane.

The chloride ion is formed when the element chlorine picks up one electron to form an anion (negatively-charged ion) Cl−. The salts of hydrochloric acid HCl contain chloride ions and are also called chlorides. An example is table salt, which is sodium chloride with the chemical formula NaCl. In water, it dissolves into Na+ and Cl− ions.

The word chloride can also refer to a chemical compound in which one or more chlorine atoms are covalently bonded in the molecule. This means that chlorides can be either inorganic or organic compounds. The simplest example of an inorganic covalently-bonded chloride is hydrogen chloride, HCl. A simple example of an organic covalently-bonded chloride is chloromethane (CH3Cl), often called methyl chloride.

Other examples of inorganic covalently-bonded chlorides that are used as reactants are:

phosphorus trichloride, phosphorus pentachloride, and thionyl chloride, all three of which reactive chlorinating reagents that have been used in a laboratory
disulfur dichloride (S2Cl2), used for vulcanization of rubber.
Chloride ions have important physiological roles. For instance, in the central nervous system, the inhibitory action of glycine and some of the action of GABA relies on the entry of Cl− into specific neurons. Also, the chloride-bicarbonate exchanger biological transport protein relies on the chloride ion to increase the blood's capacity of carbon dioxide, in the form of the bicarbonate ion.
