With the molality being 1, it doesn’t have a huge impact on changing the freezing point, but the Van’t Hoff factor increases the change in the freezing point temperature since I=4. If the molality was >1, it would be a greater change with a lower freezing point.Freezing Point Depression with Antifreeze AP Chemistry ...
When 4 is plugged into the freezing point depression equation ΔT = (4)Kf (m), the freezing point depression will be 4 times greater than without the addition of NH4PO3. It would be greater because the molality of the solution is 1 and because Kf is a constant it will result in a higher freezing point depression and significantly lower the freezing point.Freezing Point Depression with Antifreeze Yamilet's AP ...
Antifreeze is a vital element in a car’s cooling system because it lowers the freezing point, which prevents the water inside the engine from becoming solid ice.Freezing Point Depression with Antifreeze Sara's AP ...
Antifreeze works in real life to lower the freezing point of solutions of water in order to prevent them from freezing at higher temperatures.Freezing Point Depression With Antifreeze Ap Chemistry Lab ...
Freezing Point Depression and Boiling. of pure water on freezing. Antifreeze also enables the. Answer: 0.2 m \(NaCl\) (lowest freezing point). The purpose of this lab was to find the freezing point depression of water solutions of antifreeze and the molar mass of ethylene glycol.freezing point depression lab (1).doc Name Date Freezing ...

Since there is a positive freezing point depression, the freezing point of the solution is lower than the original solvent, causing the solution to freeze at a lower temperature. Sources of Error Tap water was used instead of pure, distilled water.Freezing Points of Ethylene Glycol Mixtures
You may remember that about 93% of most coolant is ethylene glycol, another few percentage points are water and or a solvent to keep rust corrosion inhibitors in solution and the remainder are those inhibitors. The inhibitors make a huge difference, and they're what all the arguments are about.Antifreeze
An antifreeze mixture is used to achieve freezing point depression for cold environments and also achieves boiling point elevation ("anti boil") to allow higher coolant temperature. Freezing and boiling points are colligative properties of a solution, which depend on the concentration of the dissolved substance.How Do Antifreeze Agents Work? | RealClearScience
The extent of freezing point depression is based on two factors: (1) The number of dissolved particles present (a feature known as a "colligative property") and (2) The nature of the dissolved particle. Exactly how this process works even including how water freezes is not well understood.
