Factors affecting solubility of a solid in a liquid
Factors affecting solubility of a solid in a liquid
Answer:
Solvent-solute attractions and temperature affect the solubility of a solid in a liquid.
Explanation:
SOLVENT-SOLUTE ATTRACTIONS
Strong attractive forces between the solvent and solute particles lead to greater solubility.
Thus, polar solutes dissolve best in polar solvents. Nonpolar solutes dissolve best in nonpolar solvents. A polar solute is insoluble in a nonpolar solvent and vice versa.
The general rule to remember is Like Dissolves Like.
TEMPERATURE
When we add heat to a substance, the kinetic energy of the molecules increases. The more energetic solvent molecules can overcome the attractive forces among solute particles. The solute particles leave the surface of the solid and move into the liquid phase (dissolve).
Thus, increasing the temperature usually increases the solubilities of substances. For example, sugar is more soluble in water at higher temperatures.
