The solubilities of ammonium bromide, NH4Br, in water at 0 °C, 20 °C, and 80 °C are as follows:

T (°C)  Sol. g NH4Br/100 g H2O
0  60.5
20  76.4
80  125

Which of the following fractional crystallization schemes would produce the highest percent yield for the recrystallization of ammonium bromide?
◦ A solution containing 50.5 g NH4Br in 100.0 g H2O at 20 °C is cooled to 0 °C.
◦ A solution containing 115 g NH4Br in 200 g H2O at 80 °C is cooled to 0 °C.
◦ A solution containing 120 g NH4Br in 100 g H2O at 80 °C is cooled to 20 °C.
◦ A solution containing 100 g NH4Br in 100.0 g H2O at 80 °C is cooled to 20 °C.
◦ A solution containing 95 g NH4Br in 175 g H2O at 80 °C is cooled to 0 °C.
