Question

What is the pH of alanine solution in which a-amino group is one-half dissociated? pKa values are pK (-COOH) 2.43 and pK(-NH₃⁺) 9.69, respectively.

science chemistry

Answer 1

Answer #1

answer : pH = 9.69

explanation:

at one half dissociationof carboxylic acid group pH = pKa1 . this means acid group pKa

so

pH = 2.43

in case of of amino group : pH = pKa2

pH = 9.69
