How is a pH meter calibrated before use?

A
  • Dipped into distilled water samples (e.g., pH 4, 7, 10).
  • Meter adjusted to read those exact values.
B
  • Dipped into standard buffer solutions (e.g., pH 4, 7, 10).
  • Meter adjusted to read those exact values.
C
  • Dipped into the titration solutions (e.g., acid, base, indicator).
  • Meter adjusted to read their expected values.
D
  • Dipped into standard buffer solutions (e.g., pH 4, 7, 10).
  • Meter adjusted to read the average value.
