Final answer:
Solubility is influenced mainly by temperature, pressure, and the chemical properties of the solute and solvent. Gas solubility decreases with increasing temperature but increases with higher pressure. The types of intermolecular forces present due to the chemical structures of the solute and solvent are key in determining solubility.
Step-by-step explanation:
The factors that affect solubility are primarily temperature, pressure, and chemical properties of the substances involved. For gases, solubility typically decreases as temperature increases. However, for most solids and liquids, solubility tends to increase with higher temperatures. When it comes to gases, pressure also plays a significant role; according to Henry's Law, there is a direct relationship between the pressure of a gas and its solubility in a liquid.
The chemical properties of the solute and solvent, like the types of intermolecular forces between them, are crucial for solubility too. For instance, solubility can vary greatly depending on whether the solvent is a polar liquid like water or a nonpolar liquid like hexane. This is why oxygen has different solubility levels in water compared to hexane.
