Solubility and Factors Affecting It
Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a particular temperature.
Practice This ConceptMain explanation
Teacher explanation
Solubility depends on the nature of the solute and solvent and also on temperature. Many solid solutes dissolve more in hot water than in cold water, while gases generally become less soluble as temperature rises.
Example
More sugar dissolves in hot tea than in cold tea, but oxygen is less soluble in warm water than in cold water.
Simple analogy
Solubility is substance-specific and temperature-linked.
Common confusion
Students often write that heating always increases solubility for every solute, including gases.
Exam tip
Always mention temperature when defining solubility because solubility values change with temperature.
