(a) Interpretation: The altered structure of the given resin that is converted into an anion exchanger is to be stated. Concept introduction: Amino acids are classified as acidic, basic and neutral according to the functional group they possesses. Acidic amino acids are those which have one more than one carboxylic acid group in its side chain and basic amino acids are those which have one or more amino group present in their side chain. Ion exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. The functional groups present in the resin act as key to exchange ions.
