Upon running a standard recrystallization in 90:10 EtOH:water you reach a point where crystals are not forming! You get very nervous as everyone else is getting excellent crystal formation. Which of the following would be an appropriate response? O Gently scratch the glass vessel with a glass stir rod to induce crystallization. O Add additional solvent to the vessel. Additional solvent will help reduce the solubility of the solid. O Stir the liquid on a stir plate with a stir bar to induce crystallization. O Dump the material in the waste, there isn't any hope at this point.
