What factors affect solubility in water?
What factors affect solubility of ionic compounds? What factors affect the solubility of gases in liquids? What factors affect the solubility of a solid? The proportionality constant needs to be experimentally determined because the increase in solubility will depend on which kind of gas is being dissolved. In order for deep-sea divers to breathe underwater, they must inhale highly compressed air in deep water, resulting in more nitrogen dissolving in their blood, tissues, and joints.
If a diver returns to the surface too rapidly, the nitrogen gas diffuses out of the blood too quickly, causing pain and possibly death. To prevent the bends, a diver must return to the surface slowly, so that the gases will adjust to the partial decrease in pressure and diffuse more slowly. A diver can also breathe a mixture of compressed helium and oxygen gas, since helium is only one-fifth as soluble in blood as nitrogen.
Underwater, our bodies are similar to a soda bottle under pressure. Imagine dropping the bottle and trying to open it. In order to prevent the soda from fizzing out, you open the cap slowly to let the pressure decrease. On land, we breathe about 78 percent nitrogen and 21 percent oxygen, but our bodies use mostly the oxygen. Unless they ascend slowly, the nitrogen can diffuse out of their blood too quickly, causing pain and even death.

Factors Affecting Solubility Solid Solubility and Temperature Solubility often depends on temperature; the solubility of many substances increases with increasing temperature. Learning Objectives Recall the relationship between solubility and temperature. Key Takeaways Key Points 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.
The increased vibration kinetic energy of the solute molecules causes them to dissolve more readily because they are less able to hold together. Key Terms solubility : The amount of a substance that will dissolve in a given amount of a solvent to give a saturated solution under specified conditions.
