Chapter 14, Problem 88UTC

Interpretation Introduction

Interpretation:

The addition of few drops of strong acid to water results in lowering of pH; the reason for no appreciable change in pH when the same numbers of drops are added to buffer should be determined.

Concept introduction:

• Strong acids will decrease pH drastically
• Buffers are used to avoid drastic pH change, since they have equilibrium formation.

To explain: Why does a buffer avoids pH change.
