Question

What is the effect of temperature on the solubility of a solid in liquid.

Answer 1

Solubility of a solid in a liquid.

• Solids are soluble in a liquid if their intermolecular interactions are similar.
• The solubility of a solid in a liquid at any temperature is defined as the maximum amount of solid (solute) in grams which can be dissolved in 100g of the liquid (solvent) to form the saturated solution at that particular temperature.
• Pressure does not affect it.

Effect of temperature

• The solubility of a solid in a liquid is significantly affected by temperature change.
• For most of the solids, solubility in water increases with rising temperature.
• As the temperature increases, the average kinetic energy of the solute molecules in the solution also increases. because of this the capacity or ability of the molecules to hold together decreases, hence they can dissolve more readily.
