What is the freezing point of an aqueous 2.65 m calcium chloride CaCl2 solution?
The freezing point of a 2.65 m calcium chloride (CaCl2) solution is approximately -5.4°C. This can be calculated using the Van't Hoff factor for CaCl2 as 3 (since it dissociates into 3 ions), in combination with the formula for freezing point depression.
Does calcium chloride affect the temperature of water?
Yes, calcium chloride increases the temperature of water.
Why calcium chloride spread on roads during winter season?
When calcium chloride is added to water, it lowers the freezing point. When spread on ice, it has the effect of melting the ice, and turning it to water. Calcium chloride is slightly less corrosive to metals that its "cousin", sodium chloride (salt), and so causes less rusting of cars, bridges, and guard rails.
Which ionic compound will lower the freezing point if 1 mol of it is added to 1 litter of water?
Adding 1 mol of any ionic compound, such as sodium chloride (NaCl) or calcium chloride (CaCl2), to 1 liter of water will lower the freezing point of the solution. This is because the presence of the dissolved ions disrupts the hydrogen bonding between water molecules, reducing the freezing point of the solution compared to pure water.
What ionic compound will lower the freezing point the most if 1 mol of it is added to 1 L of water?
A compound that dissociates into more ions when dissolved in water will have a greater freezing point depression. For example, calcium chloride (CaCl2) will lower the freezing point more than sodium chloride (NaCl) because it dissociates into three ions (Ca2+ and 2Cl-) compared to sodium chloride, which dissociates into two ions (Na+ and Cl-).
What is the freezing point of an aquerous 2.65m calcium chloride Solution?
-14.8 degrees Celsius

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.
Does calcium chloride affect the temperature of water?
Yes, calcium chloride increases the temperature of water.
If the students added 250 g of calcium chloride to 1000 g of water the freezing temperature of this solution would most likely be between?
-1.6°C and -3.0°C, depending on the molal freezing point depression constant for calcium chloride-water solution.
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.
What salt is used in antifreeze to melt ice?
The type of salt commonly used in antifreeze to melt ice is calcium chloride. It has a lower freezing point than water, making it effective in preventing the formation of ice in freezing temperatures.
What is the freezing point of water with 70000 ppm chloride?
A 7 % sodium chloride solution in water has a freezing point of -4,38 0C.

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.
What is use of calcium chloride salt?
As a desiccant (removes water), deicing road surfaces (decreases the freezing point) and also as a firming agent in food.
What is the freezing point of an aqueous 265 m calcium chloride CaCI2 solution the freezing point of pure water is 00 degrees Celsius and kf of pure water is -186 degrees Celsius over m?
-14.8 Celsius
