Answer :
From our understanding, we can confirm that the highest freezing point belongs to cacl2 or calcium chloride, the second highest is fecl3 or Iron 3 chloride, while the lowest belongs to Glucose.
What affects the freezing point of a substance?
The freezing point of a substance is determined by molecular forces. The stronger the forces that hold an object together, the higher its tendency to stay in a solid state and therefore results in a higher freezing point.
The freezing points for these substances are:
- Glucose at 146 degrees Celcius.
- Iron chloride at 306 degrees Celcius.
- Calcium chloride at 772 degrees Celcius.
Therefore, we can confirm that the highest freezing point belongs to cacl2 or calcium chloride, the second highest is fecl3 or Iron 3 chloride, while the lowest belongs to Glucose.
