<div>[[File:Carbon-dioxide.svg|thumb|400px|2D structure of carbon dioxide.]]<br />
<br />
'''Carbon dioxide''' (chemical formula CO<sub>2</sub>) is a [[Chemical compounds|chemical compound]] made up of molecules that each have one [[carbon]] atom covalently double bonded to two [[oxygen]] atoms. It is found in the gas state at room temperature. In the [[air]], carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in [[water]] and is found in groundwater, lakes, ice caps, and seawater.<br />
<br />
As the source of available carbon in the carbon cycle, atmospheric CO<sub>2</sub> is the primary carbon source for life on Earth. Plants, [[algae]] and cyanobacteria use [[energy]] from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product. In turn, oxygen is consumed and CO<sub>2</sub> is released as waste by all aerobic organisms when they metabolize organic compounds to produce energy by respiration. CO<sub>2</sub> is released from organic materials when they decay or combust, such as in forest fires. Since plants require CO<sub>2</sub> for photosynthesis, and humans and animals depend on plants for food, CO<sub>2</sub> is necessary for the survival of life on earth.<br />
<br />
About half of excess CO<sub>2</sub> emissions to the atmosphere are absorbed by land and ocean carbon sinks. These sinks can become saturated and are volatile, as decay and wildfires result in the CO<sub>2</sub> being released back into the atmosphere. CO<sub>2</sub> is eventually sequestered (stored for the long term) in rocks and organic deposits like [[coal]], [[petroleum]] and [[natural gas]]. Sequestered CO<sub>2</sub> is released into the atmosphere through burning fossil fuels or naturally by volcanoes, hot springs, geysers, and when carbonate rocks dissolve in water or react with acids.<br />
<br />
== Uses ==<br />
CO<sub>2</sub> is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery. It is also a feedstock for the synthesis of fuels and chemicals.<br />

<div>[[File:Carbonic-acid-2D.svg.png|thumb|2D structure of carbonic acid]]<br />
Carbonic acid (H₂CO₃) is a weak acid formed when carbon dioxide (CO₂) dissolves in water (H₂O). It plays a crucial role in natural processes such as the carbon cycle, ocean acidification, and respiration. While unstable in its pure form, it exists in equilibrium with dissolved CO₂ and bicarbonate (HCO₃⁻) in aqueous solutions.<br />
<br />
== Uses ==<br />
Carbonic acid's most immediate practical use lies in food preservation and preparation. Carbonated water inhibits bacterial growth while also serving as the foundation for homemade sodas and fermented drinks. The acid's mild properties make it invaluable for adjusting soil pH in small-scale agriculture, particularly for acid-loving crops like berries.<br />
<br />
In medical applications, carbonic acid solutions can function as a basic antiseptic for wound cleaning when stronger disinfectants aren't available.<br />
