Question

In recrystallization, if too much solvent is used, what will happen?
Options
A Crystals will form more quickly
B Crystals will not form because the solution is not saturated
Correct Answer
C The yield will increase
D The compound will decompose
Correct Answer

Option B is the correct answer.

Detailed Explanation

If too much solvent is used, the solution may not become saturated upon cooling, and the compound will remain dissolved. No crystals (or low yield) will form. The solvent volume should be minimal to achieve saturation.

Hint

Solution must be saturated to crystallize.
