CO2 functions as an acidic substance. Therefore, increases in bicarbonate (HCO3-) or decreases in CO2 will make blood more alkalotic. The opposite is also true where decreases in HCO3 or an increase in CO2 will make blood more acidic. Interpretation of Clinical Blood Gas Data H 2OCO2 + H2O ↔ H2CO3 ↔ H3O+ + HCO3- The concentration of carbonic acid in the body is associated with the partial pressure of CO2. When CO2 level rises, producing more H2CO3, the equilibrium produces more H3O+, which lowers the pH – acidosis. Decreasing of CO2 level due to a hyperventilation, which expels large amounts of CO2, leads to a The Piper diagram of water chemistry showed that water type of the study area belonged to NaCaHCO3 and CaHCO3 type with HCO3-as dominant anion and Na+ as dominant cation Furthermore, multivariate statistical analysis like inter-metal correlation, cluster analysis (CA) and Principal Component analysis (PCA) results revealed that geogenic and anthropogenic activities were major sources of Prevent free H+ from contributing to fluid pH Acid Base Imbalances any change in [H+] = directly relatd to [HCO3-]:[CO2] = 20:1 CHANGE in PH: -by respiratory system o wil hav abnormal [CO2] caus change in carbonic acid-generatd H+-from metabolism o wil hav abnorml [HCO3-] o reslts fr inequalty in amount of HCO3-availbl & amount of H+ generatd frm non-carbonc acd sourcs tht HCO3-must buf CHANGE Determine the concentration of CO32- ions in a 0.18 M H2CO3 solution.

For example, an increase in CO2 will result in increased carbonic acid formation (H2CO3) which leads to an increase in both HCO3- and H+ (pH). Furthermore, what does this equation mean co2 h2o h2co3 hco3 H? HCO3 : Bicarbonate is the second largest fraction of the anions in plasma. Included in this fraction are the bicarbonate (HCO3[-]) and carbonate (CO3[-2]) ions, carbon dioxide in physical solution, as well as the carbamino compounds. At the physiological pH of blood, the concentration of carbonate is 1/1000 that of bicarbonate.

The pH value at complete neutralization being about 3.8, HCO 3 ions are present.
