Concerns are associated with chronic (long-term) exposure by inhalation as may happen from thermal or chemical decomposition of formaldehyde-based resins and the production of formaldehyde resulting from the combustion of a variety of organic compounds (for example, exhaust gases). As formaldehyde resins are used in many construction materials ...
Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .
Sodium chlorite: in organic synthesis, used for the oxidation of aldehydes to carboxylic acids Sodium hydride: a strong base used in organic synthesis Sodium hydroxide: strong base with many industrial uses; in the laboratory, used with acids to produce the corresponding salt, also used as an electrolyte: Sodium hypochlorite
This is the reason for usage of formaldehyde as a preservative, as it thus prevents cellular decay and renders the tissue unsuitable for use as a nutrient source for bacteria. Formaldehyde is carcinogenic in humans and animals at excessive levels [ 6 ] [ 7 ] because the cross-linking can cause DNA to keep cells from halting the replication process.
[100] [101] For example, MgCl 2 is named magnesium chloride, and Na 2 SO 4 is named sodium sulfate (SO 2− 4 , sulfate , is an example of a polyatomic ion ). To obtain the empirical formula from these names, the stoichiometry can be deduced from the charges on the ions, and the requirement of overall charge neutrality.
Alkali metal halides, or alkali halides, are the family of inorganic compounds with the chemical formula MX, where M is an alkali metal and X is a halogen. These compounds are the often commercially significant sources of these metals and halides. The best known of these compounds is sodium chloride, table salt. [1]

The most common chloralkali process involves the electrolysis of aqueous sodium chloride (a brine) in a membrane cell. A membrane, such as Nafion, Flemion or Aciplex, is used to prevent the reaction between the chlorine and hydroxide ions. Basic membrane cell used in the electrolysis of brine. At the anode (A), chloride (Cl −) is
