Sol-gel critical concentration

{
  "id": "MLC-T-CHM-010981",
  "term": "Sol-gel critical concentration",
  "field": "Chemistry",
  "definition": "The threshold concentration of added salt beyond which a sol of particles coagulates into aggregates rather than setting as a gel. Below the threshold the particles link into a continuous network, so it marks the boundary between gelation and coagulation of the sol. It is expressed as a molar concentration of the added electrolyte.",
  "synonyms": [
    "critical concentration"
