As pH changes, the distribution of carbonate species (carbonate, bicarbonate, and carbonic acid) also shifts. In general:- At lower pH levels, carbonic acid predominates.
- As pH increases, bicarbonate becomes more prevalent.
- At higher pH levels, carbonate ions dominate.
This equilibrium is sensitive to factors such as temperature and pressure, influencing the buffering capacity of water. Understanding this relationship is essential for managing aquatic environments and addressing issues like ocean acidification.

The Closed Carbonate System - Aqion
In contrast to the open carbonate system, the total amount of dissolved inorganic carbon (DIC) remains constant when pH is varied by addition of acids or bases: 1. The closed CO 2 -H 2 O …
These natural acids play an important role in weathering in absence of human activity; behaves very much like carbonic acid. (When A + B Æ C + D, K = products/reactants = [C] [D]/[A] [B]). …
Carbonate chemistry is the most intensely studied subject of marine chemistry. It is central to: The control of seawater pH; Regulation the CO2 content of the atmosphere via the biological …
this pH range, the dominant carbonate species is bicarbonate (Figure 1). For these reasons, the alkalinity of many waters is nearly equal to the bicarbonate concentration.
We begin our discussion of the carbonate system by describing acids and bases in water, and then evolve to chemical equilibria and kinetic rates of CO2 reactions. The chapter concludes …
Notice that the charge balance (Eq 9) shows that as the partial pressure of CO2 decreases (and thus the concentrations of the other carbonate terms decrease), the pH of the solution will …

How do I quantify the carbonate system and its pH speciation?
Jul 31, 2022 · Note that the carbonic acid trends ("$H_2CO_3$" in mine, "$\alpha_0$" in Masters et al) do not have the same curves, this is especially noticeable at the high pH values where …
Three Equivalence Points (Carbonate System) - Aqion
Equivalence points (EP) represent special equilibrium states at which the amount of acid is equal to the amount of base 1. In the following we focus on the carbonate system which is just the …
The carbonate system is important for a number of reasons. Natural waters are buffered with respect to pH mostly because of the content of inorganic carbon species.
Between pH 4.3 and 8.3, only carbonic acid and bicarbonate ions are present, with the proportion of each species dependent on the pH. At pH 6.3, the concentrations of each are equal; The pH …
