A strongly alkaline solution of a monoaminodicarboxylic acid contains how many basic groups ?
3
In a strongly alkaline solution of an amino acid all of its - COOH groups are converted into −COO−. Thus a strongly alkaline solution of a monoaminodicarboxylic acid will have one −NH2 and two −COO−groups, all of which are basic in nature. Further, remember that a −NH2 is more basic than a −COO− group
