Unformatted text preview: The amino group of glycine, which has a pKa of 9.6, can exist in the protonated form (NH3+) or as the free base (NH2) because of the reversible equilibrium. R-NH3+ a R-NH2 + H+ A) In a 0.1 M solution of glycine at pH 7.0, what is the predominant species in solution. B) In a solution of glycine at pH = 9.0, what is the ratio of glycine (protonated form) to glycine (deprotonated form) at this pH. Practice Problems...
