How much would be lost?

2) minimum amount of ethanol needed?

H. The solubility of compound "X' in ethanol is 0.80 g per 100 ml at 0 C and 5.00 g per 100 ml at 78 C. ed to recrystallize a 12.00 g sample of compound "X"? How much would be lost in the recrystallization, that is, would remain in the cold solvent?

the solubility of an unkown compound of X in ethanol is found tobe .21 grams per 10 ml at 0 celcius. what is the minimum amount ofethanol needed to recrystalize a 2.0 grams sample of compound xwill remain dissolved in the cold solvent (i.e how much of thecompound x is not reconvered after recrystallization)

A. The solubitlity of an unkown compound X in ethanol is found to be 0.21 grams per 10mL at 0*C and 1.4 grams per 10mL at 78*C. What is the minimum amount of ethanol needed to recrystallize a 2.0 gram sample of compound X? After recrystallization of the 2.0 gram sample, how much compound X will remain dissolved in the cold solvent (i.e., how much of compound X is not recovered after the recrystallization)?B. Why is it important to use only the minimal amount of hot solvent needed to achieve a recrystallization? What would be the effect using too much solvent while dissolving a solid for recrystalization?C. What do you think would happen to your recrystallization solution if you did not use a preheated filter during the "hot" gravity filtration step?D. Benzyl alcohol has a boiling point of 205*C. It has solubility characteristics that would seem to make it a good choice for use as a recrystallization solvent for fluorenol (m.p. 153-155*C), but in fact benzyl alcohol is a poor choice of solvent for this recrystallization. Why do you think this is? (Hint: you do not need any other information to answer this question.)E. Explain how each of the following contaminants is removed during the recrystallization process:1. sand (inorganic contaminant)2. colored organic contaminants3. a very soluble contaminant
