Bicarbonate is naturally produced by the reaction of carbon dioxide (CO 2 ) with water (H 2 O) to produce carbonic acid (H2CO 3 ), which dissociates to a bicarbonate ion and a 3 + 2 h 3 o +. A bicarbonate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic compound .

So you are saying that when the H+ and HCO3- are formed from this process, the H+ stays as H+ in the blood and acidifies the blood but what exactly happens to HCO3 • pH = - log {H+} • The pH of seawater varies only between about 7.5 and 8.4 (i.e., slightly alkaline) • Over geological time, pH is thought to be controlled by water/mineral equilibria • Over shorter time scales (104 to 105 yrs) the CO 2 system (and its shifting equilibria) regulates seawater pH CO 2(aq) + H 2O ↔ HCO 3-+ H+ co2 + h20 --> h2co3 -->h+hco3- -when released into circulation, CO2 enters RBC and combines with H2o to form H2CO3; this carbonic acid dissocates into H ions and bicarb. free H is buffered by hemoglobin molecules and bicarb diffuses into plasma; in pulmonary capillaries, this process is reversed and CO2 is formed and excreted by lungs H2O + CO2 < -> H+CO+ < -> [HCO3-] + H+ ; Metabolic disorders are related to decreased losses, or increased ingestions or production of acids or bases. Metabolic disorders are reflected by a change in [HCO3-] Step 4A: pH elevated or decreased. pH is measured directly using an optical absorbance technique.

Chemistry CO2 +H2O <->H2CO3 <-> HCO3 + H <-> CO3+2H. it means that when CO2 is added then the equilibrium is shifted to the right, increasing HCO3 and H. Could this lead to pH reduction?
