In solution, aminoethanoic acid (glycine) can be represented as NH⁺₃ CH₂COO. This implies that it

Answer Details

The representation of aminoethanoic acid (glycine) as NH⁺₃ CH₂COO indicates that it can function as a weak acid or a weak base. The NH⁺₃ group is a positively charged ion (cation) which can act as an acid by donating a hydrogen ion (proton) to a base. On the other hand, the CH₂COO group is a negatively charged ion (anion) which can act as a base by accepting a proton from an acid. Therefore, aminoethanoic acid (glycine) can function as both an acid and a base in solution, depending on the nature of the other species present in the solution.
