ملخص الدرس

This concluding lesson examines dynamic solubility equilibrium in sparingly soluble ionic solids. It defines the Solubility Product Constant (K_sp = [M^q⁺]^p [X^p⁻]^q) and derives mathematical formulas connecting molar solubility S to K_sp (S², 4S³, 27S⁴, 108S⁵). It establishes precipitation criteria via the Ion Product Q_sp (Q_sp > K_sp precipitates) and explores the Common Ion Effect reducing solubility in qualitative analysis and kidney stone pathology.

• Sparingly soluble salts establish dynamic equilibrium between solid and dissolved ions.
• Solubility product: K_sp = [M^q⁺]^p * [X^p⁻]^q (solids omitted).
• Solubility formulas: 1:1 salt K_sp = S²; 1:2 salt K_sp = 4S³; 1:3 salt K_sp = 27S⁴; 2:3 salt K_sp = 108S⁵.
• Precipitation criterion: Q_sp > K_sp forms precipitate; Q_sp < K_sp is unsaturated.
• Common ion effect shifts equilibrium left, drastically reducing salt solubility.
• Applications: Qualitative analysis and calcium oxalate kidney stone prevention.
