Chapter 15, Problem 82(choose chapter or problem)
Amino acids are the building blocks for all proteins in our bodies. A structure for the amino acid alanine is All amino acids have at least two functional groups with acidic or basic properties. In alanine, the carboxylic acid group has Ka 4.5 103 and the amino group has Kb 7.4 105 . Because of the two groups with acidic or basic properties, three different charged ions of alanine are possible when alanine is dissolved in water. Which of these ions would predominate in a solution with [H] 1.0 M? In a solution with [OH] 1.0 M?
