Because now, instead of trying to bring solely water to a boil, you are trying to bring a solution of water and salt to a boil. And the salt solution (however weak a solution it is) has a different boiling point, chemically, from a straight H20 solution, right? THUS- it takes a few minutes longer to bring to a boil.

As adding salt , you are accually trying to make saltwater which is a impurity. and due to salt boiling point isnt the same temperature as distilled water, it will affect the water and make it have a higher boiling and lower melting point.

Water is two elements. The salt adds a third compound that throws it into a solution-the same thing can be done with a tablespoon of cooking oil.

table salt is sodium chloride, often times its mixed with different salts like magnesiun salts which makes the salt take up water, salt is a chemical compound and at the same time as boiled with water (H2O) it undergoes a chemical reaction, and ions, complicated ions which reason those transformations Na+, Cl-, H+, OH- are the ions, compunds like NaOH, HCl are formes etc, NaCl + H2O ------------------- NaOH + HCl
