SUMMARY
The solubility of carbon disulfide (CS2) decreases with increasing temperature, contrary to the expectation that higher temperatures would enhance solubility due to increased ionic product of water (Kw). The discussion highlights that while Kw increases with temperature, the weak solute-solvent interactions of CS2, a linear molecule with minimal dipole interactions, contribute to its declining solubility. Additionally, the evaporation rate of CS2 rises with temperature, further reducing its concentration in solution.
