For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
What are the 5 factors that affect solubility?
What are the 5 factors that affect solubility?
- Temperature. Basically, solubility increases with temperature.
- Polarity. In most cases solutes dissolve in solvents that have a similar polarity.
- Pressure. Solid and liquid solutes.
- Molecular size.
- Stirring increases the speed of dissolving.
How do you know if solubility increases or decreases?
Thus, increasing the temperature increases the solubilities of substances. For example, sugar and salt are more soluble in water at higher temperatures. But, as the temperature increases, the solubility of a gas in a liquid decreases. As temperature increases, the average kinetic energy of the gas molecules increases.
