A saturated solution can dissolve more solid solute on heating. What is the most suitable reason?
Answer and explanation
Correct answer: Solubility of many solids increases on heating
Saturation is always defined for particular conditions, including temperature. If the temperature is raised, the equilibrium solubility of many solid solutes increases, so additional solute can dissolve in the same solvent. This is not because the solvent disappears or pressure suddenly becomes large. The direction is substance-dependent, but the stated behaviour is common for many solids.
