Many other stable and metastable oxides of carbon are known but are rarely encountered. The simplest oxocarbon is carbon monoxide CO. Carbon monoxide is a colorless, tasteless gas that is slightly lighter than air. It is toxic to humans and animals when encountered in higher concentrations, despite the fact that it is produced in the metabolism and is thought to have some biological functions. Carbon monoxide consists of one carbon and one oxygen atom connected by a triple bond.
The distance between the carbon and oxygen atom is CO has three resonance structures, but the structure with the triple bond is the best approximation of the real distribution of electron density in the molecule. CO is naturally produced by the human body as a signaling molecule. Abnormalities in its metabolism have been linked to a variety of diseases, including hypertension and heart failure.
CO is present in small amounts in the atmosphere, mostly as a result of the burning of fossil fuels and fires. Through natural processes in the atmosphere, it is eventually oxidized to carbon dioxide CO 2.
Carbon dioxide, or CO 2 , is a naturally occurring linear compound composed of two oxygen atoms covalently bonded to a carbon atom. The compound is centrosymmetric and so has no net dipole. CO 2 is colorless; at high concentrations it has a sharp, acidic odor, but at lower concentrations it is odorless.

A couple of years ago we posted a blog about the American Red Cross getting confused between carbon dioxide CO 2 and carbon monoxide CO in a household initiative. We have seen a lot of stories about charities, the media and other organisations not seeming to know the difference. In Melbourne, Australia, a plumbing company offered carbon dioxide testing following the death of a family killed by a carbon monoxide leak.
Find out more about carbon monoxide. Carbon Dioxide sensing is crucial for a number of different industries, including HVAC , landfill , horticulture , controlled atmosphere storage and packaging , metal heat treatments , TOC and many more.
Each of these applications would not be possible without precise CO2 measurement. If you are interested in finding out more about specific applications of CO2 sensing, why not have a browse of the following articles…. Carbon Monoxide sensing using a CO sensor is equally important because detection cannot be done by vision or smell alone. It is necessary because it can prevent carbon monoxide poisoning which can cause loss of consciousness, seizures of even deaths. Furthermore, CO sensing takes place across a number of other applications, which you can read about by following the links below.
According to their properties, it is also possible to categorize them as acidic, basic, neutral and amphoteric oxides.
Acidic oxide can react with bases and form salts. Ex: sulfur trioxide SO3. Basic oxides react with acids and form salts. Ex: sodium oxide Na2O. Neutral shows neither acidic or basic properties; thus they do not form salts upon reacting with acids or bases.
Ex: carbon monoxide CO. Amphoteric oxides have both acidic and basic properties; therefore, they react with both acids and bases to form salts. Ex: zinc oxide ZnO. Dioxide is an oxide containing two atoms of oxygen in its molecule.
