- For my lab experiment it was a reaction between p-aminophenol and acetic anhydride to make acetaminophen through crystallization. The question asks why should you use a minimum amount of water to rinse the conical vial whole transferring the purified acetaminophen to the Hirsch funnel? I honestly have no idea I thought if the crystals formed it didn’t matter how much water you rinsed the vial with. If you could do xplain why the amount of water matters I’d greatly appreciate it!In chemistry class, a student conducted an investigation about factors affecting the solubility of copper (II) sulfate (CUSO4) in water. The data was recorded in the table below. Trial Factors Compound not stirred Temperature: 60ºC Large crystals Compound was stirred 2 Temperature: 25°C Large crystals Compound was not stirred 3 Temperature 25°C Large crystals Compound was stirred Temperature 60°C Finely crushed powder Which trial will have the slowest rate of dissolving? Explain the reasoning for your answer.When choosing a pair of solvents for a mixed-solvent recrystallization, what factor is most important?

What…Which of the following are properties of a good recrystallization solvent? Check all correct answers. Group of answer choices boiling point of solvent < melting point of crystals boiling point of solvent > melting point of crystals Crystals are soluble in solvent at low temperature and soluble at high temperatures. Crystals are soluble in solvent at high temperatures but insoluble or slightly soluble at low temperatures. Solvent boiling point is about room temperature. Impurities should be either soluble at all temperatures or insoluble at all temperatures. An abundant amount of crystals must be recoverable from the solvent.
