Solubility vs. Dissolution: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 20, 2024
Solubility is the ability of a substance to dissolve in a solvent; dissolution is the process of a substance dissolving in a solvent.
Key Differences
Solubility refers to the maximum amount of a substance that can dissolve in a given amount of solvent at a specific temperature. Dissolution is the process by which this substance actually dissolves in the solvent.
Solubility is a property of a substance and is often quantified as grams per liter. Dissolution, on the other hand, describes the action or process of a substance becoming solvated.
Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent. The rate of dissolution can be influenced by stirring, particle size, and temperature.
Solubility is a static measure, indicating how much solute can be dissolved. Dissolution is a dynamic process, involving interactions between solute and solvent molecules.
In chemical terms, solubility determines how substances interact in a solution. Dissolution is a key step in the process of a substance integrating into a solution.

FAQs
How does temperature affect dissolution?
Temperature can increase the rate of dissolution for most solids in liquids.
What is solubility in chemistry?
Solubility in chemistry is the ability of a substance to dissolve in a solvent to form a homogeneous solution.
Is solubility a constant value?
Solubility can vary with different conditions like temperature and pressure, but it's a specific value under given conditions.
Can dissolution be a chemical change?
Yes, when bonds are broken and new ones are formed, dissolution involves a chemical change.
Can solubility be increased?
Yes, often by changing the temperature or pressure, or by altering the chemical nature of the solvent.
What factors influence the rate of dissolution?
Factors include stirring, surface area of the solute, temperature, and the nature of the solvent and solute.
How do pressure changes affect gas solubility?
Increased pressure usually increases the solubility of gases in liquids.
What's the difference between solubility and solvation?
Solubility is the capacity to dissolve, while solvation is the process of surrounding solute particles with solvent molecules.
Can all liquids dissolve solids?
No, the ability to dissolve solids depends on the chemical nature of both the liquid and the solid.
Are solubility and concentration the same?
No, solubility is the maximum amount that can dissolve, while concentration is the actual amount of solute in a solution.
Can dissolution be reversed?
In some cases, like evaporating the solvent, dissolution can be reversed.
What is an example of dissolution in daily life?
Dissolving sugar in coffee or tea is a common example of dissolution.
Is it possible for something to be insoluble?
Yes, some substances do not dissolve in a particular solvent and are considered insoluble.
What is an unsaturated solution?
An unsaturated solution contains less solute than the maximum amount that can be dissolved.
Does pH affect solubility?
Yes, pH can affect the solubility of certain substances, especially those that are weak acids or bases.
What role does dissolution play in medication?
Dissolution is crucial for medication absorption in the body from oral tablets or capsules.
What is a saturated solution?
A saturated solution occurs when no more solute can dissolve at a given temperature and pressure.
How is solubility used in industries?
Solubility is important in pharmaceutical, food, and chemical industries for product formulation.
Does stirring always speed up dissolution?
Stirring usually speeds up dissolution by moving dissolved particles away from the solute surface.
Is solubility important in environmental science?
Yes, solubility influences the distribution and bioavailability of chemicals in the environment.
