How does adding salt to water affect the boiling point and melting point?

Answer 1

Adding salt to water affects its density meaning that the particles have to move more to reach a boiling point. The temperature therefore has to increase to make the particles move more and evaporate.

Answer 2

Adding sugar or salt in water increases its boiling point . you might be knowing that before boiling water absorbs the heat which is known as latent heat of vaporisation . so when impurities get added they take up the heat absorbed by water which in turn causes water to absorb more heat to attain its boiling point resulting in an increase in the boiling point

Answer 3

When salt is added to water, the boiling point rises. When the temperature of the water increases, the molecules move faster and this increases the number of collisions. As a result of this more vapor gas molecules are released. However, when salt is added, there is a decrease in the number of collisions between water molecules, causing less vapor molecules to be released. So more energy (a higher temperature) is needed in order for salt water to boil than in pure water.

Answer 4

The addition of a salt usually increases the boiling point of water slightly.

Answer 5

... gives higher boiling and lower melting point.
