		This figure is often quoted as the dissociation constant of carbonic acid, although this is ambiguous: it might better be referred to as the acidity constant of carbon dioxide, as it is particularly useful for calculating the pH of CO solutions.
		The carbonic acid that remained was characterized by infrared spectroscopy.
		Pure carbonic acid is predicted to be stable in the gas phase, in the absence of water, with a calculated half-life of 180,000 years.

		Further examples of the 1-substituted propane-1,3-diphosphonic acids used in accordance with the invention may be derived from the associated organic derivatives referred to hereinafter, more especially from the esters, whose hydrolysis results in the formation of the 1-substituted propane-1,3-diphosphonic acids and phosphinic acids.
		All the 1-substituted propane-1,3-diphosphonic acids used in accordance with the invention are obtained by combining the vinyl phosphonic acid and vinyl phosphinic acid derivatives with the C-H-acid phosphonic acid and phosphinic acid derivatives by addition.
		the vinyl phosphonic acid esters, the vinyl phosphinic acid esters or the corresponding amides, are reacted with the C-H-acid activated phosphonyl compounds, i.e.

		O taken away from it and is expelled from the red blood cell as CO Then the carbon dioxide is permitted to be expelled out of capillaries and into the lungs where it is expelled.
		The equilibrium between carbon dioxide and carbonic acid is very important for controlling the acidity of body fluids, and almost all living organisms have an enzyme, carbonic anhydrase, which catalyzes the conversion between the two compounds, increasing the reaction rate by a factor of nearly a billion.

		I've thought a CO2 polymorph with a silica-type structure (i.e., C tetrahedrally coordinated with O, with C-O-C bridges linking each vertex of each tetrahedron) might be a really useful substance.
		Unfortunately, although organic compounds containing C tetrahedrally coordinated with oxygen exist (esters of "orthocarbonic acid"), no one has succeeded even in synthesizing the orthocarbonate ion (CO4^4-, analogous to the well-known isolated silicate tetrahedron SiO4^4-), much less in polymerizing such tetrahedra.
