  "id": "MLC-T-CHM-010087",
  "term": "Reference value pH standard",
  "field": "Chemistry",
  "definition": "A solution with a precisely known and reproducible pH value, used for calibrating pH meters and establishing the pH scale. These standards are typically prepared from specific buffer solutions with high purity and well-defined compositions. The pH values of these standards are determined by primary methods, such as the Harned cell.",
