supersaturated etymology

Etymology:

  • Super- (Latin): Above or beyond
  • Saturated (Latin): Soaked or filled

Meaning:

A solution that contains more solute dissolved in it than would normally be possible at that temperature and pressure.

Origin:

The term "supersaturated" was first used in the mid-19th century by the German chemist Justus von Liebig. Liebig was studying the solubility of salts in water and observed that some solutions could dissolve more solute than expected based on the known solubility limit. He coined the term "supersaturated" to describe these solutions that were "above saturated."

Usage:

Supersaturated solutions are unstable and over time, the excess solute will precipitate out of the solution, returning it to a saturated or even unsaturated state. Supersaturated solutions can be used in various applications, such as crystal growing, electroplating, and pharmaceutical formulations.
