When carbon dioxide dissolves in water, it undergoes a multistep equilibrium process, with Koverall = 4.5x10⁻⁷, which is simplified to the following:(c) What is [CO₃²⁻] in rainwater (Ko of HCO₃⁻ = 4.7 × 10⁻¹¹) ?

Respuesta :

The extensive acid electricity of intact carbonic acid suggests that it is an essential protonation agent below physiological conditions.

The carbonate ion (CO32−) is a strong base. It is a conjugate base of the weakly acidic bicarbonate (IUPAC name hydrogen carbonate HCO3−), itself a strong conjugate base of the still weakly acidic carbonic acid.

What does carbonate do in water?

Carbonates are moderately strong bases. Aqueous solutions are basic because the carbonate anion can accept a hydrogen ion from water. CO32− + H2O ⇌ HCO3− + OH− Carbonates react with acids, forming salts of the metal, gaseous carbon dioxide, and water.
