Mention three factors affecting the rate of dissolution.
Solution is a homogeneous mixture of two or more components. A solution is formed by the combination of solute and solvent.
For example, Common salt in water.
Solute- Common salt , Solvent – Water
Definition of solubility or dissolution
The quantity of solute required to saturate 100g of solvent at a particular temperature is called solubility.
Factors affecting solubility
When the particle become smaller, the surface are increases. When the surface area exposed to solvent increases, solubility increases.
2. Stirring
Stirring brings more of the solvent in contact with the solute. Thus rate of formation of solution increases.
3. Temperature
The solubility of a gas in a liquid always decreases with rise in temperature. But the solubility of most of the solids in water usually increases with rise in temperature.
