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.

Why there is turbidity when coppper sulfate solution is treated with ammonium hydroxide?

The turbidity is due to the formation of the insoluble copper hydroxide.


What property of a particular solute towards a solvent is necessary for recrystallization to occur?

The coolness of the solution causes recrystallization. This is because the solute becomes solid at a higher temperature than the solvent.


Obtaining pure salt from rock salt?

Rock salt is ground, dissolved in water, the solution is filtered and this solution is refined by successivelyprocesses of crystallization/recrystallization, to obtain sodium chloride (table salt) 99,99 %; and finally this salt is iodized and some anticaking substances are added.


How you purify salt?

Salt is refined by the filtration of the water solution and repeated crystallization/recrystallization processes.

How do you indicate that a solution is a alkaline solution or a base?

By using a universal pH indicator. If the pH indicator turns from red to blue, it will shows that it is a alkaline solution or a base, if the pH indicator turns from blue to red, it shows that it is an acidic solution. Hope its use full info for you>>>:)d
