WebHCO₃⁻ + H₂O → H₂CO₃ + OH⁻ base + acid → Conj A + Conj B. We see that HCO₃⁻ becomes H₂CO₃. It has one more H atom and one more + charge (-1 + 1 = 0). So H₂CO₃ is the conjugate acid of HCO₃⁻. The H₂O becomes OH⁻. It has one less H atom and one … Let us take the example of Bicarbonate being placed in water to create Carbonic … What would happen if OH-ions were added to a very basic solution?

WebJan 28, 2009 · [A] = 2 [CO3--] + [HCO3-] + [HO-] - [H+] So the alkalinity as HCO3 for the 1ppm CaCO3 addition should have been 2*0.6 ppm HCO3. One for the HCO3- and one for the HO-. Then the alkalinity as CaCO3 is also 1 ppm. But nobody else seems to see it like that. Either everybody copied from the same source or I'm on the wrong track here.
