  "id": "MLC-T-CHM-003382",
  "term": "Donnan equilibrium",
  "field": "Chemistry",
  "definition": "A state of equilibrium achieved across a semipermeable membrane that separates two solutions, one of which contains charged macromolecules that cannot pass through the membrane. The unequal distribution of permeable ions across the membrane creates an electrical potential difference. This phenomenon is observed in biological systems, such as cell membranes, and in synthetic polymer systems.",
