  "term": "Standard concentration",
  "field": "Chemistry",
  "definition": "A reference concentration used to define the standard state for solutes in solution, typically 1 mol/L (or 1 M). This value is employed in thermodynamic calculations to establish a consistent baseline for comparing the properties of different solutions. It is a hypothetical concentration used for defining standard chemical potentials and activities.",
