Summary Introduction
To write: The dissociation reaction of acetic acid and, label the acid, base, H+ acceptor, and H+ donor in the equation
Concept introduction:
A buffer is a solution that maintains a constant pH. It is an aqueous solution made up of a weak acid and its corresponding base. For example, carbonic acid regulates pH in human blood.

Glycine hydrochloride (Cl− H3N+CH2COOH) is a diprotic acid that contains a carboxylic acid group and an ammonium group and is therefore called an amino acid. It is often used in biochemical buffers. Solve, In analogy with Figure , sketch the titration curve of this diprotic acid.
The pl of alkaline phosphatase is 4.5; the pl of the DEAE cellulose is 10.5. We used a buffer of pH 7.4 to run a DEAE-cellulose as anion exchange column? Explain how did this work?
