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.

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.
Which temperature scale has 100 degrees between freezing and boiling?
The Celsius temperature scale has 100 degrees between freezing and boiling.
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
In the Fahrenheit temperature scale what is the boiling point of water?
In atmospheric pressure (ie at sea level), water boils at 100 degrees Celsius.
Does freezing temperature change at higher altitudes?
Elevation has minimal affects on the freezing point of water as it doesn't deal with gas molecules as boiling does. Elevation affects the boiling point of water because the air pressure changes with elevation.

What processes is most affected by pressure freezing or boiling or melting?
Boiling. (:
In the Fahrenheit temperature scale what is the boiling point of water?
In atmospheric pressure (ie at sea level), water boils at 100 degrees Celsius.
What is the customary measure unit of temperature?
In most of science it is the Celsius degree. There are 100 of these degrees between the freezing point and boiling point of water at standard pressure (sea level). The other common or customary unit is the Fahrenheit degree. There are 212 of these degrees between the freezing and boiling points of pure water at standard atmospheric pressure.
Can the freezing point be lower than its boiling point in a constant pressure?
At a constant pressure, the freezing point is always going to be lower than the boiling point.
Is freezing boiling or melting most affected by pressure?
Boiling point is most affected by pressure. Note that freezing point and melting point are in fact the same.
Why is centigrade scale a good name for the celsius scale?
The scale is based on the freezing point and the boiling point of water (at some standard pressure); between those two temperatures, the scale is divided into 100 intervals. Centi means hundred.The scale is based on the freezing point and the boiling point of water (at some standard pressure); between those two temperatures, the scale is divided into 100 intervals.

What does Fahrenheit freeze at?
On the Fahrenheit scale, the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point 212 °F (at standard atmospheric pressure), placing the boiling and freezing points of water exactly 180 degrees apart.
What effect does chloride salt have on water temperature?
Sodium Chloride- table salt - lowers the water's boiling and freezing point.
What are the freezing point and boiling point of water in the celsius?
Freezing = 0 degrees Celsius (0oC) Boiling = 100 degrees Celsius (100oC)It depends on the object you are talking about.The boiling point of water is 100 degrees Celsius, and its freezing point is 0 degrees Celsius.
