Addition of any substance to water will increase the boiling point and lower the freezing point.

(A minor clarification: the substance has to dissolve. Adding insoluble materials like sand doesn't change the boiling or freezing point.)

Why does the boiling point of water change when salt is added?

By adding salt it means that you are adding an impurity into the water. Impurities can lower the boiling point, while increasing its melting point.


What is the boiling point of pure water with salt?

When salt is added to water, the boiling point of the water increases. The exact boiling point depends on the concentration of salt in the water. As a general rule, for every 58.5 grams of salt dissolved in 1 liter of water, the boiling point will increase by 1 degree Celsius.


Does salt lower the boiling point?

Yes, Salt also lowers the freezing point of water, and lowers the boiling point of water. Add salt to a boiling pot of water and it immediately boils faster/harder at the location that the Salt hit the water.


Do salt water boil faster than non salt water?

Adding a salt to a substance changes its boiling and freezing points, but it lowers its freezing point and raises its boiling point. So, salt water actually takes more heat to boil because the salt has raised the boiling point.


What are the independent and dependent variables of adding salt water to boiling water?

The quantity of salt added to water is under your control and it will change the boiling point of water,i,e. the temperature of water. So quantity of salt is an independent variable while the temperature of water is dependent variable, when other factors are kept constant.


Why does it take the water longer to boil when it has salt in it?

When salt is added to water, it increases the boiling point of the water, requiring it to reach a higher temperature to boil. This is because the salt disrupts the formation of water vapor molecules, which slows down the boiling process.


When salt is added to boiling water at 100 degrees Celsius will the water boil faster or slower?

Adding salt to boiling water will actually make the water boil slower. Salt increases the boiling point of water by raising its boiling point temperature. As a result, it will take longer for the water to reach the new, higher boiling point temperature and thus boil.


Why does it take less time for water to boil when sugar is added?

Actually, it's when salt is added; it decreases the boiling point of water.


Does salt evaporate in boiling water?

No, salt does not evaporate in boiling water. When water boils, it turns into steam, leaving behind the salt in the water. Salt does not have a low enough boiling point to evaporate along with the water.


What does the boiling of salt water compare to the boiling point of fresh water?

The boiling point of salt water is higher than that of fresh water because the presence of salt increases the boiling point of a solution. Salt water requires more energy to come to a boil compared to fresh water at the same atmospheric pressure.

Can salt water is used to determine the boiling point of water?

No, salt water cannot be used to accurately determine the boiling point of ultrapure water. Salt water boils at a slightly higher temperature than pure water; salt water can be used to determine the boiling point of salt water.
