Explain why during the recrystallization of p-dibromobenzene the turbidity of the hot solution was used as an indicator for the ratio of ethanol to water used?
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.
What is the difference between Real and Ideal solution?
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.
What is ideal solution?
The solution that is most suited for something or best of all.
What are the properties of an ideal recrystallization solvent?
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.
What are ideal solution?
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.

What is the ideal keyword density for NaOH solution in order to optimize its effectiveness?
The ideal keyword density for NaOH solution to optimize its effectiveness is typically around 10-15.
What is the ideal pH level for normal saline solution?
The ideal pH level for normal saline solution is around 7.4, which is close to the pH level of human blood.
What is the ideal water to salt ratio for making a brine solution?
The ideal water to salt ratio for making a brine solution is generally around 5-8 salt by weight.
What is the ideal baking soda to vinegar ratio for creating a homemade cleaning solution?
The ideal baking soda to vinegar ratio for creating a homemade cleaning solution is 1:1.
Is water and ethanol a ideal solution?
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
