SUMMARY

Calculating the solubility product constant (Ksp) at a specific temperature is feasible if the Ksp at another temperature and the enthalpy change (\Delta H) are known. The process requires determining the entropy change (\Delta S) to accurately compute the new Ksp value. This method is essential for understanding temperature-dependent solubility in chemical systems.

PREREQUISITES
  • Understanding of Ksp and its significance in solubility equilibria
  • Knowledge of thermodynamic principles, specifically \Delta H and \Delta S
  • Familiarity with temperature dependence of chemical equilibria
  • Basic skills in performing calculations involving thermodynamic equations
NEXT STEPS
  • Study the Van 't Hoff equation for temperature dependence of Ksp
  • Learn how to calculate \Delta S from \Delta H and Ksp values
  • Research the impact of temperature on solubility equilibria in various salts
  • Explore advanced thermodynamic concepts related to solubility and phase changes
USEFUL FOR

Chemistry students, researchers in physical chemistry, and professionals involved in materials science or environmental chemistry who are interested in solubility and thermodynamic calculations.

Is it possible to calculate Ksp at a certain temperature if you know Ksp at a different temperature and \Delta H?
 
Physics news on Phys.org
Yes, it's possible.
 
But you'd need to get delta S first right?

EDIT: nvm, got it.
