Think back to what you learned in this course about solutions and intermolecular forces. Why don't these to "mix" together (in other words, make a homogenous solution) when combined. Why do they separate into layers
The addition of anhydrous calcium chloride to the crude product obtained from the separation procedure often results in the product becoming clear what causes this clearing
