This change in freezing point is referred to as freezing point depression, one of several colligative properties. In this experiment, we will use the colligative property of freezing point depression of water to chill another mixture (ice cream) to the solid state]]> 2016-04-17 16:46:11 UTC https://padlet.com/80047441/icecreamswirl/wish/106183471 80047441 https://padlet.com/80047441/icecreamswirl/wish/106183799 We had a quart size Ziploc and filled it with a mixture of milk, half and half, sugar, and vanilla. then we had to double bag the quart size bag. After, we added two scoops of ice in a gallon sized bag and took its temperature. Then, we added rock salt and placed the milk mixture bag into the ice. To protect our hands, we placed the bag in a shoe box. Then we shook the box vigorously until the mixture solidified. Finally, we took the final temperature of the ice/salt mixture and ate the ice cream.]]> 2016-04-17 16:52:05 UTC https://padlet.com/80047441/icecreamswirl/wish/106183799 80047441 https://padlet.com/80047441/icecreamswirl/wish/106183864 Freezing point depression is the process in which adding a solute to a solvent decreases the freezing point of the solvent.  ]]> 2016-04-17 16:53:00 UTC https://padlet.com/80047441/icecreamswirl/wish/106183864 80047441 https://padlet.com/80047441/icecreamswirl/wish/106183919 The longer we shook the box the lower the temperature dropped.]]> 2016-04-17 16:53:58 UTC https://padlet.com/80047441/icecreamswirl/wish/106183919 80047441 https://padlet.com/80047441/icecreamswirl/wish/106183966 Adding a solute to a solvent lowers the freezing point of that solvent.

This allows the ice cream to evenly freeze. ]]> 2016-04-17 16:56:45 UTC https://padlet.com/80047441/icecreamswirl/wish/106184067 80047441 https://padlet.com/80047441/icecreamswirl/wish/106184166 Sucrose does not dissolve as quickly in water as sodium chloride.
