* Description/Instructions
Solubility refers to how much solute can be dissolved in a solvent at a given temperature and pressure. It is expressed in grams of solute per 100 grams of solvent. The dissolving process is called solvation. Solutes are dissolved in solvents. Solute particles mix with solvent particles. But at some point during the solvation process, the rate at which the solute mixes with the solvent stabilizes and no more solute can be dissolved. When this happens, the solution is saturated.

Increasing the temperature of the solution increases its solubility. More solute can be dissolved because the particles are moving faster, which increases the number of collisions between solute and solvent particles. Supersaturated solutions are made by increasing the temperature of the solution.

Pressure affects the solubility of gaseous solutes. Solubility of a gas increases as external pressure increases. When the temperature increases, solubility of a gas decreases.

The rule for the solvation process is “like dissolves like.” Polar solutes dissolve in polar solvents and nonpolar solutes dissolve in nonpolar solvents. This is why some clothes have to be dry-cleaned. The cleaners use nonpolar solvents to dissolve oil and grease stains because they won’t dissolve in water.
