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.


What effect does chloride salt have on water temperature?

Chloride salts dissolve in water without significantly affecting the temperature of the water. However, when chloride salts are used for de-icing roads or sidewalks, they can cause the surrounding environment to become colder by lowering the freezing point of water.


How does the presence of dissolved sodium chloride affect the boiling and freezing point of water?

Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.


What in salt makes ice melt?

Salt is made up of Sodium Chloride (NaCl). In this case, it is the Chloride (Cl) that breaks the composition of water, and causes the freezing point of water to be lowered. Without Chloride, the freezing point of water is 32 degrees Fahrenheit (0 Celcius). With 10% of Sodium Chloride (salt), water freezes at 20 Fahrenheit. With 20% of Sodium Chloride, water freezes at 2 Degrees Fahrenheit.


What will be the freezing point change of the resulting solution if we dissolve 1 mole of aluminium chloride AlCl3 in 1000 g of water?

The freezing point is with -7,4 oC.


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.


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?

b. lower freezing point A 0.5 M solution of potassium chloride will have a lower freezing point compared to pure water due to the presence of solute particles which disrupt the formation of ice crystals.


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-).


Will NaCl's affect the freezing point of a solution make the freezing point increase?

No, adding NaCl to a solution will actually lower the freezing point of the solution. This is because the presence of dissolved ions from the salt disrupts the formation of ice crystals, causing the freezing point to decrease.


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.


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.
