Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.the Flemish chemist Jan Baptist van Helmont observed that when he burned charcoal in a closed vessel, the mass of the resulting ash was much less than that of the original charcoal.
As part of the carbon cycle, plants, algae, and cyanobacteria use light energy to photosynthesize carbohydrate from carbon dioxide and water, with oxygen produced as a waste product.) is a colorless and odorless gas that is vital to life on Earth.This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms.Being diprotic, carbonic acid has two acid dissociation constants, the first one for the dissociation into the bicarbonate (also called hydrogen carbonate) ion (HCO is a weak electrophile.Its reaction with basic water illustrates this property, in which case hydroxide is the nucleophile. For example, carbanions as provided by Grignard reagents and organolithium compounds react with CO Carbon dioxide is colorless. At higher concentrations it has a sharp, acidic odor.Carbon dioxide can be obtained by distillation from air, but the method is inefficient.
Industrially, carbon dioxide is predominantly an unrecovered waste product, produced by several methods which may be practiced at various scales.
Liquid carbon dioxide forms only at pressures above 5.1 atm; the triple point of carbon dioxide is about 518 k Pa at −56.6 °C (see phase diagram at left). at extreme pressure (40–48 GPa or about 400,000 atmospheres) in a diamond anvil.
This discovery confirmed the theory that carbon dioxide could exist in a glass state similar to other members of its elemental family, like silicon (silica glass) and germanium dioxide.
Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater.
It is present in deposits of petroleum and natural gas.
He used this phenomenon to illustrate that carbon dioxide is produced by animal respiration and microbial fermentation.
