An ideal solution for crystallization should provide high purity and yield, ensuring that the desired compound is effectively separated from impurities. It should allow for controlled nucleation and growth rates to produce well-defined crystal shapes and sizes. Additionally, the solvent system should be easily removable and compatible with the subsequent processing or application of the crystallized product. Lastly, the method should be scalable and reproducible for consistent results in various laboratory or industrial settings.
ethanol alone is not a good solvent for this substance recrystallization and the compound has a very low solubility in hot or cold water.so ethanol and water are mixed together as solvent for crystallization of p-dibromobenzene that is soluble in the hot solvent mixed.so the turbidity of the hot solution shows the good mixture of ethanol and water as solvent.
there is no interaction between the components in ideal solution whereas in non-ideal solution there is interactions between components. ideal solution obeys Raoult`s law whereas non-ideal solution do not obeys it. no volume change occurs on mixing due to no interaction in ideal solution whereas in non-ideal solution volume change occurs.
The solution that is most suited for something or best of all.
An ideal recrystallization solvent should have high solubility for the compound at high temperatures to dissolve the impurities and low solubility at low temperatures to allow the compound to crystallize out. It should also be chemically inert towards the compound, easily evaporated to recover the purified compound, and have a boiling point lower than the melting point of the compound.
An ideal solution is a solution where all the components are completely miscible with each other in all proportions, resulting in a single-phase mixture. This means there is no change in enthalpy or volume when the components are mixed, leading to ideal behavior according to Raoult's Law. Ideal solutions are often used in chemistry to simplify calculations and models.
Whether a solution is ideal depends on the specific context and criteria being considered. An ideal solution typically addresses the problem effectively, is feasible to implement, and meets the needs of stakeholders without causing significant negative consequences. However, in practice, most solutions may have trade-offs and limitations, making it rare to find a truly "ideal" solution. Thus, evaluating the effectiveness and practicality of a solution is essential.
An ideal recrystallizing solvent should have a high solubility for the target compound at elevated temperatures and low solubility at room temperature to facilitate crystallization. It should not react with the compound or impurities and must be volatile enough for easy removal. Additionally, the solvent should be inexpensive, non-toxic, and ideally, have a boiling point that allows for simple evaporation. Lastly, it should dissolve impurities well at both high and low temperatures to ensure a purer final product.
