- a. The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 " is best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: HO + :Ö: Bicarbonate is crucial for the control of body pH (for example, blood pH 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs.
