Questions: (1 pt each) remember these questions will be checked for completion only. if you have questions about them, make sure to ask your instructor. 1. suppose the material that you are recrystallizing fails to crystallize out of the cold solvent. what would you do to recover the material from solution? 2. suppose you obtain 1.0g of product from the hydrolysis of 1.3 ml of methyl salicylate. calculate your % yield. 3. describe the characteristics of a good recrystallization solvent. explain how the rate of crystal growth can affect the purity of a recrystallized

1. To recover he material completely the best way is to evaporate the solvent and try to recrystallize it once more. Or you can add less polar solvent or that which wont dissolve your compound to precipitate it.

2. The density of methyl salicylate is 1.174 g/cm3 so 1.3 mL is 1.3/1.174=1.107 g so in theory after hydrolysis you are supposed to obtain  so the yield will be

3. The best variant is when your compound is practically insoluble in cold solvent and dissolves fairly in hot solvent (example sodium acetate in water). The slower the crystals grow, the better for their purity. If compound crystallizes fast occlusion can take place and you won't get pure crystals but that ones with solvent inside and impurities.

Explanation:

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
