saturation level

Saturation level refers to the point at which a substance, such as a solution or material, can no longer absorb or incorporate more of a particular element or compound. In solutions, it means the maximum amount of solute (like salt or sugar) that can dissolve in a solvent (like water) at a given temperature. Beyond this point, additional solute will not dissolve and can form separate particles or crystals. In other contexts, it can describe the maximum capacity of a material to hold or transmit a resource, such as blood oxygen levels or signals in a communication system.
