Chapter 16, Problem 62QAP

Interpretation Introduction

Interpretation:

The component of a buffered solution that consumes added strong base should be determined.

Concept Introduction:

There can be two main kinds of buffer systems depending on the pH values that one needs to achieve in preparation of the buffer solutions. The two main kinds are acidic and basic buffer solutions. In both these kinds of buffer solutions there are two main constituents.

In an acidic buffer a weak acid and its conjugate base are the two main components in the buffer system. An example of such an acidic buffer system is the acetic buffer system. Acetic buffer contains acetic acid (CH₃ COOH) as the weak acid and acetate ions (of the form of sodium acetate, CH₃ COONa) as the conjugate base (with respect to acetic acid) of the buffer system.
