Calcium chloride dissociates and gets in between the water molecules. Its kind of like trying to stack a bunch of books with marbles in between.

Will NaCl's affect the freezing point of a solution make the freezing point increase?
The freezing point of water solutions containing sodium chloride is lower.
What is the freezing point of an aqueous 2.65 m calcium chloride CaCl2 solution?
-14.8
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Because the mixture NaCl + CaCl2 has a lower melting point that NaCl.
What has a higher boiling point calcium chloride or sulfur trioxide?
Calcium chloride
Which ionic compound will lower the freezing point if 1 mol of it is added to 1 litter of water?
Sodium Chloride
Why calcium chloride added in sodium chloride to lower the melting point?
The heat of dissolution for calcium chloride in water is greater compared with the same paremeter for sodium chloride; consequently the process of dissolution need more heat from the environment and the freezing point of the water solution is lower.
Does calcium chloride raise or lower boiling point and freezing point of water at standard pressure?
The boiling point will increase with the addition of CaCl. I did an experiment where I added 13.002g of CaCl to 30mL of H2O and it raised the boiling point to 112oC. The initial reaction of CaCl and water produces heat in itself. The solution I used raised the water temperature to 75oC before the heat source was added to the water. I haven't experimented with the freezing point yet but I am assuming it will lower it because Calcium Chloride is an ionic salt and there is a tendency in ionic salts to lower the freezing point.

The freezing point of water solutions containing sodium chloride is lower.
What is the freezing point of an aquerous 2.65m calcium chloride Solution?
-14.8 degrees Celsius
What is the freezing point of an aqueous 2.65 m calcium chloride CaCl2 solution?
-14.8
How does the amount of salt in a solution affect its freezing point?
Increasing the concentration of sodium chloride in water the freezing point is lower.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
When compared to pure water what will a 0.5 M solution of potassium chloride have a. lower boiling point b. lower freezing point c. higher capor pressure d. lower osmotic pressure?
a lower freezing point
When should you apply rock salt?
Rock salt (or calcium chloride, potassium chloride) is applied to roads with ice or snow; the freezing point of water is lowered.
Melting point of NaCl lower by the addition of calcium chloride?
because of common ion effect
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Because the mixture NaCl + CaCl2 has a lower melting point that NaCl.
What has a higher boiling point calcium chloride or sulfur trioxide?
Calcium chloride
