Solubility Equilibrium (Ksp)
Learning Time: 5-15 hours
Content: Solubility equilibrium is a subject that investigates the saturation state of a solid substance in solution and the solubility product constant (Ksp). This area covers the definition of solubility equilibrium, Ksp calculations, factors affecting solubility (common ion effect, pH), precipitation and dissolution conditions, and practical applications. TYT focuses on basic Ksp, while AYT focuses on complex equilibrium systems. The current 2025 curriculum also covers environmental cleanup and recycling technologies. Learning this topic forms the basis for chemical purity and industrial processes.
