The driving potential for the crystal growth during crystallisation is the _______________ of the solution?
Correct answer: C. Super-saturation
- A. Concentration
- B. Viscosity
- C. Super-saturation
- D. Density
Explanation
Crystal growth requires a supersaturated solution, which provides the chemical-potential driving force for solute molecules to deposit on the crystal surface. Concentration alone is not the driving force unless it is expressed relative to saturation concentration.
