what causes percent yield to be high

  • 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.
