CO2 + H2O —> H2CO3 <—> H+ + HCO3- Carbon dioxide reacts with water to form carbonic acid, which dissociates in water to hydronium and bicarbonate anion. This increases the concentration of H+ in solution, reducing the pH. The pKa of carbonic acid is 6.4, which is about the pH ...
K(HCO3) + HBr = KBr + H2(CO3) (HCOO)2Ca + CO2 + H2O = CaCO3 + HCOOH C5H12 + Br = C5H11Br + HBr KMnO4 + Li2SO4 = K2SO4 + LiMnO4 CO2 + KOH = CO3KH HAuCl4 + Na3C6H5O7 = H3C6H5O7 + NaAuCl4 Mn(NO3)2 + NaOH = Mn(OH)2 + NaNO...

When phytoplankton assimilate CO2at the low concentrations existing at high pH their uptake rates may be limited by diffusion transport. Dehydroxylation of HCO3-to CO2will, however, reduce the effect of transport limitation. In this paper the equation for diffusion with chemical reaction that produces...
The cells themselves may have also contributed to the alkalization of the pH 7.2 medium by the exchange of intracellular HCO3− for extracellular Cl- by the Cl-/HCO3− antiporter [36]. Nevertheless, literature on the pH in the interstitia of tissues is scarce. In most interstitia, the...
因此,H+和循环水中的碱度直接的反应为和OH-、CO32-、HCO3-之间的反应。 第二:H+和循环水中的碳酸H2CO3和溶解态二氧化碳CO2(水的反应。循环水中的CO2有两种形式,即碳酸H2CO3形式和溶解态二氧化碳CO2(水的形式。CO2(水的大气中的CO2交换,它们之前的关系符合亨利定律。在通常的滴定分析中测得的游离CO2是CO2(水...

where k and n are the temperature-dependent rate constant and reaction order for aragonite precipitation4. Note, besides CO2diffusion, transport of HCO3−into the calcifying fluid via Cl−/bicarbonate anion transporter has also been proposed as a potential source of carbon for coral calcification...
Intramucosal pH (pHi) was calculated using the Henderson- Hasselbalch equation: pHI ϭ 6.1 ϩ log [HCO3]/(mCO2 ϫ 0.031). Where 6.1 is the negative logarithm of the dissociation coefficient of carbonic acid and 0.031 is the solubility of CO2 in plasma, mCO2 is the mucosal CO2 ...
