Question

An _____ is a species that can act as either an acid or a base. aliphatic species​ allotropic species​ isomeric species​ amphiprotic species​ ​aromatic species

Answer 1

The correct answer for the above question is Amphiprotic species.
Amphiprotic species are species that have both acidic and basic properties. A good example is an amino acid since it contains both a weak acid and a weak base functional group. Amphoteric oxides such as aluminium oxides can react with both acids and bases to produce salt and water are also examples.
