Chapter 22, Problem 26R

To determine

To Compare: The given pair of terms- pH and buffer.

Explanation of Solution

Introduction:

The pH of a solution determines its acidity or basicity. Buffers maintain a certain pH.

The pH of a solution is a measure of the ${\text{H}}^{+}$ ion concentration in the solution. Buffers are solutions that contains ions that resists a pH change on addition of a small amount of acid or base to it. Buffers help maintain the pH of essential solutions.

Conclusion:The pH of a solution is a measure of the concentration of ${\text{H}}^{+}$ ions in the solution, while, buffer is a solution that resist change in pH when minimum amount of acid or base is added to it.
