Multiple Choice

The pH meter should be standardized before each use. Which option best reflects this preparation?

Explanation:
Standardizing the pH meter before use anchors its readings to known reference values provided by buffer solutions. This process adjusts the meter so its response matches established pH standards, accounting for any electrode drift or sensitivity changes. By aligning the instrument to these known points, you ensure the measured pH reflects the true value at the measurement temperature. Warming relates to temperature effects, and cleaning addresses contamination, but neither establishes the correct reference point for pH. Therefore, standardizing best reflects the required preparation.
