Question
1. Acetylsalicyclic acid has a melting point of 135-135.5celsius.For the following conditions, what would you expect for the meltingpoint if :
a)The above was mixed as a 50:50 mixture with pure salicylic acid(which was a melting point of 156-158 celsius)
b)Acetylsalicyclic acid is mixed as a 50:50 mixture with purebenzoin (which has a melting point of 132-33 celsius)
2. Why do we need to use a minimum volumeof hot solvent for a recrystallization? Why can't it be excessvolume or cold?
a: I presume this has to do with saturation?
3. 1.8g of crude benzoic acid was recrystallized in anappropriate solvent with a percent recovery of 76%, how muchbenzoic acid was recovered?
a: Is it simply 1.8g x .76?
