Verified step by step guidance1
Understand that solubility refers to the maximum amount of a substance (solute) that can dissolve in a solvent (like water) at a given set of conditions.
Recognize that temperature often affects solubility because increasing temperature generally increases the kinetic energy of molecules, allowing more solute to dissolve.
Consider atmospheric pressure: it mainly affects the solubility of gases in liquids, but has little effect on solids or liquids dissolving in water.
Note that the size of the container does not affect solubility because solubility is an intensive property, independent of the amount of solvent or container size.
Understand that the color of the compound is unrelated to its solubility; color is a physical property that does not influence how much of the compound dissolves.
