"Bicarbonate anion"Bicarbonate anion is trigonal planar with respect to the central carbon atom....

Explanation:

You gots HO-C(=O)-O^(-)HO−C(=O)−O−. There are three regions of electron density round the central carbon, and VESPER insists that these adopt a trigonal planar geometry to minimize the interaction of lone electron pairs. Each /_O-C-O=120^@∠O−C−O=120∘ to a first approx.
