See all questions in Factors Affecting Solubility. This is the most common situation where an increase in temperature produces an increase in solubility for solids.
The use of first-aid instant cold packs is an application of this solubility principle. A salt such as ammonium nitrate is dissolved in water after a sharp blow breaks the containers for each. The dissolving reaction is endothermic - requires heat. Therefore the heat is drawn from the surroundings, the pack feels cold. The effect of temperature on solubility can be explained on the basis of Le Chatelier's Principle. Le Chatelier's Principle states that if a stress for example, heat, pressure, concentration of one reactant is applied to an equilibrium, the system will adjust, if possible, to minimize the effect of the stress.
This principle is of value in predicting how much a system will respond to a change in external conditions. Consider the case where the solubility process is endothermic heat added. An increase in temperature puts a stress on the equilibrium condition and causes it to shift to the right.
The stress is relieved because the dissolving process consumes some of the heat. Therefore, the solubility concentration increases with an increase in temperature. If the process is exothermic heat given off. A temperature rise will decrease the solubility by shifting the equilibrium to the left.
Solids and liquids show almost no change in solubility with changes in pressure. But gases are very dependent on the pressure of the system. Gases dissolve in liquids to form solutions. This dissolution is an equilibrium process for which an equilibrium constant can be written. As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase.
Therefore, the solubility of a gas decreases as the temperature increases. Solubility curves can be used to determine if a given solution is saturated or unsaturated. This means that the solution will be saturated since 48 g is less than 80 g.
Now the solution is unsaturated since it contains only the original 80 g of dissolved solute. Skip to main content. Search for:. How Temperature Influences Solubility Learning Objectives Describe the influence of temperature on the solubility of solids in water.
