10. What are the crystallization’s initial materials? a) Liquid, aqueous solution, emulsion b) Gas, aqueous solution, foam c) Aqueous solution, melt, glass or gel d) Solid, gas, melt, solid aerosol
Answer: c Explanation: Aqueous solutions, whether in the form of a melt, glass, or gel, are typically homogeneous, single-phase, and amorphous. This could make crystalline product formation much easier, as long-range ion diffusion may not be required, and the product would form at a lower temperature.
