Solubility of a solute X is 20 g / 100 g of water at 450C and 10 g / 100 g of
water at 250C. What happens when a solution of 15 g of X in 100 g of water at
450C is cooled to 250C.
Solubility:
20g/100 @ 450 C.
10g/100 @ 250 C.
So if we place 15g/100 it will be dissolved at 450. When cooled to 250, how much can the 100 mL hold? Obviously it can dissolve 10 g. How much do you have? 15 g, right? So it will dissolve 10 but there are 15 g there, what do you think will happen?
