Question

How is the boiling point of water affected when salt is added to it? e. Write any two factors that affect the rate of evaporation.​

Answer 1

Answer:

Explanation:

i)

When you add salt to water, sodium chloride dissociates into sodium and chlorine ions. These charged particles alter the intermolecular forces between water molecules. In addition to affecting the hydrogen bonding between water molecules, there is an ion-dipole interaction to consider. The ion-dipole interaction is stronger than the hydrogen bonding between the water molecules, so more energy is needed to move water away from the ions and into the vapor phase

ii)

Concentration of the evaporating substance in the air

Temperature of the liquid.

Exposed surface area of the liquid.
