slower is the wrong word, but I know what you're asking. pure water at standard pressure has to overcome two basic forces to jump into the gas phase. first, the air pressure of 101.k kPa is pushing down on the surface, holding those water molecules down. Next, all the water molecules are so polar, due to their bent shape, and the very electronegative bonds (oxygen electronegativity value of 3.5 vs. hydrogen's of 2.1). The polar water molecules are very attracted to each other due to the interactive force called hydrogen bonding.
For the concept of vapour pressure and boiling.
Vapour pressure of water is depend on temperature. At 100 oC, vapour pressure of water will be at the same as atmospheric pressure so it boil.
Salt, is in solid state and virtually had no vapour pressure. Presence of salt mean the vapour pressure is diluted. For such solution to have vapour pressure of atmosphere, it require increase of Temperature from normal boiling point.
The boiling point of salt water is higher than the boiling point of pure water.
You can boil water out of salt b/c water has a lower boiling point than salt...but I don't think the other way is possible.
Maximum temperature of water is the boil temperature. But the boil temperature depends on atmospheric pressure and on salt content of the water. The more atmospheric pressure the more temperature. Boil temperature in mountain can be 60 centigrade. At normal (not high) land it usually 100 centigrade. But, as I said, temperature also depends on salt content (amount of salt) in the water. The more salt the less boil temperature. This way to take high grade boil when you cooking put the salt in to the water at the last moment of cooking.
To Flavor The Noodles When salt is dissolved in water, it lowers the boiling point of the water slightly. This means that the water should boil faster as it boils at a lower temperature. The effect is small, however.
Depends on how much and what salt, but definitely higher than pure water.
salt water will boil. also will freshwaer
Yes, drinking water does boil at a lower temperature than salt water.
The salt acts as a catalyst which prevents the water from boiling at the lower temperature.
No. A liquid with a lower density will boil before one with a higher density (assuming identical heat sources). Fresh water will boil at a lower temperature than salt water.
Adding salt does not effect the temperature.Answer:Adding salt does not change the temperature at the time you add the salt, but it raises the temperature at which the water will boil

A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.
When water has a substance dissolved in it, it freezes at a lower temperature. Salt water has salt dissolved in the water, so it freezes at a lower temperature than fresh water.
