Key Concepts: Solubility Curves

Core Definitions

• Solubility Curve: A graph showing the relationship between solubility of a substance and temperature.
• Reading the Curve: Points on the line = saturated; below = unsaturated; above = supersaturated.
• Endothermic Dissolving: Most solid solutes show increasing solubility with temperature (curve slopes up).
• Gas Solubility: Gas curves slope downward — gases become less soluble as temperature increases.
