2. Explain why you had to cool your solution before isolating the alum. Does the temperature of the ice bath affect your percent yield? If so, explain how

Solution

It is so because, cooling the solution allows crystals formation (which is alum here) .Therefore, a suitable cooling temperature must be provided to the solution for formation of the crystals.

Yes, it will affect the percent yield because if the temperature is not low enough then it will effect percent yield because the crystals will not form properly and fully.
