Under normal conditions, when salt is added to water THE SALT DISSOLVES IN THE WATER THEREBY INCREASING THE BOILING POINT OF THE WATER.
When salt is added to water, the sodium and the chlorine ions in the salt separate and attach themselves to water molecules, this leads to the dissolution of the salt. Dissolving salt in water automatically increase the temperature at which the water will boil; the temperature will be greater than 100 degree Celsius.
