If you add any solute (salt) to the water, the boiling point will increase.
It is called 'Boiling point elevation'
Boiling-point elevation is a colligative property that states that a solution will have a higher boiling point than that of a pure solvent. The change in boiling point can be determined by the equation ΔTB.P.=n·i·Kb·m, where m is the molality of the solute, i is the Van 't Hoff factor (the number of dissolved particles the solute will create when dissolved), and Kb is the boiling-elevation constant unique to each solvent.
A common mis-attribution of the use of boiling-point elevation is adding salt when cooking foods to elevate the temperature of the water before it boils. However, the temperature increase caused by the amounts of salt added when cooking is generally not enough to raise the temperature by a single degree. The salt is added simply to season the food and prevent pasta from sticking.
A few Kb values are... Water = .512
Carbon tetrachloride = 5.03
Chloroform = 3.63
Benzene = 2.53
Carbon disulfide = 2.34
Diethyl ether = 2.02
Camphor = 5.95

During the boiling process the temperature does not change!!!
The amount of heat absorbed by the water is used to transform water into steam (state transformation: liquid -> gas).
Before and after this transformation the absorbed heat causes the temperature change, but not during the state transformation.

When you add something to water (eg. salt for cooking or anti-freeze to your car radiator) you are altering the boiling or freezing point of the water since the additive dissolved within changes the chemical properties of the water.
Salt makes water boil at a higher temperature (which is good for cooking) and anti-freeze lowers the freezing point of your car radiator (to prevent a frozen and possibly cracked engine block or radiator hose).

once you dissolve yet another compound in water it ought to change the boiling and freezing element of the water. you could also change the boiling temperature of water by technique of fixing the quantity of rigidity (i.e., decrease rigidity = decrease boiling element). it truly is taken great thing about in rigidity cookers and the bane of those cooking at larger altitudes.
