Saturated Solution

C = Ksp/[dissolved ions]; at saturation: Q = Ksp
Quick Reference
Formula / NotationC = Ksp/[dissolved ions]; at saturation: Q = Ksp
Also Known AsSaturated aqueous solution, fully dissolved solution

What is Saturated Solution?

A solution containing the maximum amount of dissolved solute at a given temperature and pressure. No more solute can dissolve at equilibrium. Adding more solute creates a dynamic equilibrium between dissolving and crystallizing. Supersaturated solutions contain more than the equilibrium amount.

Formula & Notation

C = Ksp/[dissolved ions]; at saturation: Q = Ksp

Other Names / Synonyms: Saturated aqueous solution, fully dissolved solution

Properties & Characteristics

A saturated solution contains the maximum amount of dissolved solute at a given temperature; any additional solute will not dissolve. At saturation, the rate of dissolution equals the rate of crystallisation (dynamic equilibrium). The solubility product constant Ksp describes this equilibrium for sparingly soluble salts. Temperature changes can shift the equilibrium and alter the saturation point.

Uses & Applications

Saturated solutions are used in crystallisation to purify compounds. They form the basis of pickling and preservation techniques in food science. Saturated brine solutions are used industrially in the chlor-alkali process.

Safety Information

Saturated solutions of toxic or corrosive compounds retain their hazardous properties. Supersaturation can cause rapid crystallisation (bumping) that poses a physical hazard in laboratory settings.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
