This solution, like any other solution, is composed of a solute (in this case, carbon dioxide) and a solvent (water). Water is a fine solvent for polar molecules, as it is a polar solvent; on the other hand, carbon dioxide molecule, like most carbon compounds, is non-polar (like oil). Thus, carbon dioxide does not make such a great solute for water, so it needs to be forced or compressed into the water, and it tends to separate immediately after, being drag by a repulsive force.

Carbon dioxide’s tendency to get away makes the solution become fizzy, sparkling, and effervescent club soda. This solution contains a certain amount of carbonic acid and the process of dissolving one into another is called carbonation and it happens under pressure. CO2 + H2O = H2CO3. In carbonation, the solute is gas, while the solvent is liquid. The process becomes instable once pressure is reduced: You see that all the time in carbonated soft drinks; the bubbles you can observe in your drink are carbon dioxide released from the homogenous mixture. H2CO3 = CO2 + H2O.

The first carbonation technology implemented for the production of bottled carbonated pops is connected to the founder of Schweppes Company, at the end of the 18th century. Mr. Schweppe moved to London and his business flourished there, as the Brits seemed to love his tonic. At the beginning of the 20th century, the earliest home carbonation system was invented and first sold in the UK. The 70s and the 80s were perhaps the greatest years of seltzer, as people particularly enjoyed to "get busy with the fizzy”.

The process also occurs spontaneously in nature. You may have noticed that rain is usually a little bit acidic: While falling down from the sky, raindrops come across carbon dioxide that exists in the air and dissolve it.
