Chapter 16, Problem 60QAP

Interpretation Introduction

Interpretation:

The two main components of a buffer system should be identified.

Concept Introduction:

A buffer solution can be defined as an aqueous solution which is capable of resisting pH changes upon addition of small amounts of a strong base and a strong acid as well as upon dilution by distilled water (or in general water). The action that corresponds to keep the resistance to any changes on pH is known as “ buffering”. A buffer solution has a distinct definite pH value and hence is valuable in reaction conditions where one needs to maintain the pH value at a constant value. Blood is an example of a natural buffer which usually maintains the pH value around 7.4.
