🤓 Based on our data, we think this question is relevant for Professor Savizky's class at COLUMBIA.

Solution: The structure of the CO32– ion can be described in the Lewis formulation by these structures below. This means that  a) two carbon-to-oxygen bonds are single bonds; the third is a double bond. b) three independent forms of the CO32– ion coexist in equilibrium. c) the electrons must be rapidly exchanging among the three forms.  d) the CO32– ion exists in only one form: an average of the three principal structures shown.
