Carbonated drinks known as sparkling, fizzy, seltzer and soda waters are thought to impact the waistline. A new study weighs in, but don’t expect too much.

Figure 4. Carbonic acid and its conjugate base, bicarbonate ion. Because both the acid and base in a buffer solution are conjugates of each other, the reaction can move in whichever direction it needs ...

A hydrogen atom from the carbonic acid bonds to the carbonate ion in ocean water and creates a bicarbonate ion (HCO-3) which the shell-making organisms can’t use.

Carbon dioxide dissolves in (and reacts with) water, forming carbonic acid. As this acid forms, it breaks down (dissociates) into a hydrogen ion and a bicarbonate ion. The hydrogen ion (produced when ...

“The hydrogel is highly porous and filled with water, which facilitates the rapid transport of the small bicarbonate ions across the material,” explains Zhuyuan Wang, a researcher in Zhang’s tea ...

A more promising solution is the use of reactive carbon capture (RCC), which involves dissolving CO2 in alkaline solutions, like bicarbonate, and converting it directly into formate ions.
