Chapter 16, Problem 10ALQ
Interpretation Introduction
Interpretation:
How a buffered solution resists changes in the pH of the solution should be explained?
Concept Introduction:
A buffered solution is a solution that resists a change in its pH on addition of a strong acid or base. A solution is buffered by the presence of a weak acid HA and its conjugated base A-.
