What is the purpose of using a GOOD solvent in the mixed solvent technique for recrystallization?
What is the purpose of using a GOOD solvent in the mixed solvent technique for recrystallization?
- To dissolve the compound very well even at room temperature (correct)
- To prevent the recrystallization process
- To create a permanent cloud in the solution
- To dissolve the compound only at boiling temperature
