Answer #1

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)

    please answer all parts I am trying to check my answers. Recrystallization of Acetanilide Recrystallization is an important method used by chemists to purify solid compounds. When a chemist conducts a chemical reaction as shown in Scheme 1, it will rarely go to 100% completion, and will frequently produce byproducts. These byproducts and some of the unreacted starting materials will be present in the end as impurities. Chemists need ways to remove these unwanted impurities so they can isolate their...
