Chapter 3.3, Problem 3CC
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.
