Answer:
Acetic acid ([tex]CH_{3}COOH[/tex]) can release only one single H+ ion .
Therefore we can say that acetic acid has only one pKa value.
Amino acids have one -COOH( carboxylic group) group and one -NH2 (amino group) group which can both release one single H+ ion.
Explanation:
Acetic acid ([tex]CH_{3}COOH[/tex]) can release only one single H+ ion .
Therefore we can say that acetic acid has only one pKa value.
Amino acids have one -COOH( carboxylic group) group and one -NH2 (amino group) group which can both release one single H+ ion.
In amino acids -[tex]NH_{2}[/tex] group becomes [tex]-NH_{3}^{+}[/tex] in the presence of acids.
in the presence of bases [tex]-COOH[/tex] becomes [tex]-COO^{-}[/tex]
Therefore two pKa values can be observed amino acids.
