Chemistry- Aspirin lab question , My question is what would have caused us to have a high percent yield, but low purity? What went wrong? The aspirin was completely dry, so it wasn't that there was water making the aspirin heavier, giving us a higher actual yield and therefore a higher percent yield, but obviously there was something in our .

Crystallization and the effect on yield and purity | Yeah ,
I think that it would more likely produce low yield of crystals The amount of solute that dissolves depends on the amount of solvent, if you don't add enough solvent to your original sample, not all of the solute will dissolve and this will reduce your yield when you recrystallize the solute
Percent yield is simply the actual yield (the mass of resultant) divided by the theoretical yield (the most that can be attained) Therefore, the possibility of having a percent yield greater than, Star Gazing
