Question

Okay, my answer is wrong, but what is the correct answer and why.

Attempt 1 Feedback Select the statement that will help produce more pure crystals during recrystallization. Incorrect Seed the solution with the solid product that forms on the spatula While it is important that the solid Make sure that the solid dissolves completely in the cold solvent dissolves in hot solvent rather than Add a little extra solvent after the crystals have completely dissolved. melting, this will not lead to more pure crystals upon recrystallization. Consider that impurities are soluble and the desired product is insoluble at low temperatures in a good recrystallization solvent. If there is more solvent available to keep the impurities in solution, fewer impurities will be trapped in the crystals that form upon cooling O Make sure that the solid dissolves in the hot solvent, rather than melt. O O O O

Answer 1

recrystallization based on the principle that solute should be insoluble at room temperature so if impurities will also be insoluble at room temperature then crystal will be impure hence to make sure the impurities are soluble at room temperature we add little bit of extra solvent during dissolution of the solute.
