Answer:

We got #HCO_3^-#, i.e. the conjugate base of carbonic acid, #H_2CO_3#...

Explanation:

And bicarbonate ion has a Lewis structure of...#(O=)C(OH)(O^-)#

#H_2CO_3# might be better represented as #CO_2*H_2O#, i.e. dissolved carbon dioxide...the presence of greater concentrations of carbonic acid in the world's oceans might mean a drop in mean ocean #pH#...tho I haven't seen good data to support this phenomenon.

What general effect do you think a drop in #pH# would have on the ocean's coral reefs, the which are insoluble #CaCO_3(s)# to a first approx....??
