You have 1 M (1 mol/L) solution of amino acid. This amino acid has an alpha carboxyl group with pKa = 2.0 and an alpha- amino group with pKa = 10.0. The pH of the solution is 7.0. Calculate the concentration of the molecular form of this amino acid that has carboxyl group protonated (COOH) and, at the same time, the amino group deprotonated (NH2).
