← ScienceWhich outcome occurs when a concentrated Calcium Chloride solution cools rapidly below its solubility limit?
A)Spontaneous precipitation of solid, crystallization✓
B)Reduced ion mobility within solvent
C)Endothermic dissolution heat absorption
D)Diminished osmotic flow through membranes
💡 Explanation
Supersaturation occurs because reaching equilibrium lags actual conditions; therefore, once the solubility drops with temperature, spontaneous precipitation via CRYSTALLIZATION relieves the supersaturation pressure, rather than ionic changes or thermal effects under kinetic constraints.
