1. what is the minimum volume of boiling water needed todissolve .2 g of sodium benzoate? the olubility of sodium benzoatein boiling water is 1 gram per 1.4 mL. about how much sodiumbenzoate at 25 C is 1 gram per 1.8 mL. Calculate the max mass ofsolid sodium benzoate that can be recovered when the cooledsolution is filtered.

2. why would mixed solvents be used for recrystallization?

3. explain why the melting point of pure phthalic acid is higherthan that of pure naphthalene, when both have nearly the sameweight.

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
