Water boils when the molecules are able to overcome the vapor pressure of the surrounding air to move from the liquid phase to the gas phase. With that being said when you add salt that increase the amount of heat needed for water to make the transition( chemistryabouteducation). The more salt you add to water, the more you raise the boiling point. For control…
