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.

ideal type
The ideal keyword density for NaOH solution to optimize its effectiveness is typically around 10-15.
The ideal pH level for normal saline solution is around 7.4, which is close to the pH level of human blood.
The ideal water to salt ratio for making a brine solution is generally around 5-8 salt by weight.
The ideal baking soda to vinegar ratio for creating a homemade cleaning solution is 1:1.
No this is not an ideal solution, because water and alcohol (ethanol) molecules interact rather complex resulting in eg. an azeotropic boiling point at 96% mixture
