The Many Forms Of Carbon Dioxide

By David Justine on March 20, 2012

Carbon dioxide is known by many names. These are common names, industrial names which are all derived from its multiple uses. Some of these are Carbonic acid gas, Carbonic anhydride, Carbonic oxide, Carbon(IV) oxide and Dry ice (solid phase).

It is a very peculiar gas in the manner that it's slightly acidic which when dissolved in water forms a weak acid, carbonic acid. It is a weak electrophile which explains its affinity to water as well as its attraction to other nucleophiles.

It is a colorless odorless gas at room temperatures but in high concentrations it has a sharp acidic odor. This is why in most industrial installations Carbon Dioxide Detectors are required to detect its presence and sustained build up. They have become common place in most factories today due to safety regulations and labor laws becoming more stringent.

This was one of the first constituents of air to be discovered. Jan Baptist von Helmunt observed the burning of charcoal in a closed vessel. This is the famous experiment repeated in high school chemistry classes to prove that chemical reactions do not change the overall molecular weights of the products. Toxic gas detectors work on a similar principle and interpret the change in gas concentration in its vicinity.

Toxic gas detectors are usually battery operated hand held devices and used in chemical installations as to alert individuals of alarming increase in noxious gases. Toxic gas detectors transmit warnings via many methods, such as flashing lights, warning bells and automated shut down of the plant when it's very serious.

This gas in low concentrations though is fairly harmless and even households employ Carbon Dioxide Detectors to detect fires and alert the nearest fire station in the event of an outbreak. It is a byproduct in many reactions. The most common ones are combustion of fossil fuels, ammonia synthesis, production of hydrogen by steam reforming and fermentation. Combustion of any carbon based substance yields carbon dioxide as a byproduct which is why during house fires there is a huge buildup of carbon dioxide alarm.

Since most substances are hydrocarbon and are flammable carbon dioxide is produced. In industrial areas though to keep its buildup to a minimum carbon dioxide detector are used in conjunction with soda lime. Soda lime is a know naturally occurring substance that has a high affinity to absorb this gas..

Analox are a technology company specialising in the manufacture of carbon dioxide sensors, gas detectors and carbon monoxide alarm Gases monitored include: carbon dioxide, oxygen, carbon monoxide and hydrocarbons.
