Question
Chapter 2, Problem 16E
Summary Introduction
To calculate: The pK of the weak acid in a given concentration.
Concept introduction: pH of a solution is denoted as the negative logarithm of the hydrogen ion concentration of that solution. The pH in a solution decreases as H+ ion concentration increases in the solution. The pH of a neutral aqueous solution is 7, if it exceeds 7 it is a base, if it below 7 it is an acid. The pH is a concentration measurement of hydrogen ions present in an aqueous solution. pKa is the acid dissociation constant of element that is a more related to pH of that element and has a particular value.

Please help. Thank you
What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
