What are the advantages of using a solvent pair for recrystallization? Select all that apply. You can quickly make the solution supersaturated by adding more of the solvent with greater dissolving power. You can calculate the precise amounts of the solvents needed for recrystallization. You can quickly make the solution supersaturated by adding more of the solvent with less dissolving power. You don't have to know the exact amounts of the solvents needed. You can control the solubility of the substance in the mixed solvent.

Explanation / Answer

Ans. You can make the solution supesaturated by adding more of the solvent with less disolving power. (Crystal grow in such slovent easily due to less solubility)

You do not have to know the exact amount of solvents needed. (It depends)

You can control the solubility of the substance in the mixed solvent. ( Solvent lik benzene or toluene will help in crystallization)
