While most solid solutes become more soluble as temperature rises, certain substances exhibit an exothermic dissolution process where their solubility decreases as the temperature increases.

The analysis

The claim states that the solubility of certain solid solutes decreases as temperature increases. This is a well-established chemical phenomenon (exothermic dissolution, or retrograde solubility for specific compounds like certain salts and polymers). Paper [2] demonstrates exothermic dissolution for lithium carbonate, Paper [8] discusses exothermic dissolution of inert solids in mixtures, and Paper [9] explicitly notes an inverse relationship between temperature and solubility for certain macromolecular systems. Therefore, the claim is supported by the retrieved literature.
