Definition

1. Noun:
   • The point of maximum concentration: The stage at which a solution can dissolve no more of a particular solute at a given temperature and pressure.

Usage

• Scientific/Technical Context: Used primarily in chemistry and physics to describe the limit of solubility or absorption.
  • The chemist added salt to the water until it reached its saturation point and no more would dissolve.

Related Phrases

Related Idioms
