An amino acid has a COOH group with a pK of 2.5 and an amino terminal group with a pK of 9.0. Sketch the pH profiles of the three significant protonation states (roughly plot fraction of unprotonated, singly and doubly protonated states vs pH)
I have tried graphing the Base concentration vs pH but the graph doesn't seem to make any sense. Would you please enlighten me. Thank you so much
