WebDec 9, 2015 · Studies show that as carbon dioxide levels have increased in the atmosphere over the past two centuries, seawater has become less saturated with aragonite and calcite. The average pH of seawater has fallen from about 8.2 to 8.1, about a 30 percent increase in acidity on pH’s logarithmic scale. WebDayton’s water treatment plants use conventional lime (calcium oxide) softening processes. After softening, the pH of the water is adjusted using carbon dioxide. The water is fluoridated and then later disinfected using with chlorine. Rapid sand filtration is the final step in the water treatment process.

Carbon dioxide, pH, and alkalinity - Ocean Acidification
WebCarbon dioxide reacts with water. The carbon atom of CO 2 is electron poor with an oxidation state of IV. The electron rich oxygen of water donates an electron pair to the carbon. After proton transfer from water to an oxygen of the CO 2 unit, carbonic acid is formed. The reaction between water and dissolved carbon dioxide is reversible and rapid. WebWater exposed to air contains carbonic acid, H 2 CO 3, due to the reaction between carbon dioxide and water: \[\ce{CO2(aq) + H2O (l) \rightleftharpoons H2CO3(aq)} \nonumber \] Air-saturated water has a hydronium ion concentration caused by the dissolved \(\ce{CO_2}\) of \(2.0 \times 10^{−6}\; M\), about 20-times larger than that of pure water ...
