A study succeeds in isolating carbonic acid in gaseous form and maintain stable

An international investigation in which participated the Consejo Superior de Investigaciones Científicas (CSIC) has been isolated for the first time the acid molecule carbon in a gaseous state and to study their kinetic stability at low temperatures. The results indicate that this chemical may be present in certain environments and objects in the universe.
Carbonic acid is an essential molecule in many chemical processes such as regulation of blood pH or acidification of the oceans, among others, present in carbonated drinks like soda.
"In this investigation we found that the carbonic acid molecule can exist in gas phase, and being isolated, being kinetically stable at low temperatures without decomposing. We also noted that in vapor form adopts two different geometries, in addition to form molecules of two units of the same chemical structure, known as dimers, "says Galvez.

Demonstration of kinetic stability of the molecule gaseous state is a major development in basic science research, but also in the field of astrophysics.

"The conditions of low temperature and pressure that occur in different environments and stellar objects remind us that this molecule could be present in these bodies or regions of space. For example, within our solar system, we could find carbonic acid in the atmosphere that surrounds the nucleus of comets, called coma, or at the poles of Mars. In these places there is a lot of water and carbon dioxide could lead to the formation of the molecule, "he says Galvez.
