Over time, numerous applications for the addition of salt in water have been established and the process of adding salt in water has become a regular exercise wherever water has to be boiled around the world (bradley, 2006. The flash point of the liquid is at 111°c, while its boiling point and freezing points are 197°c and -13°c, respectively ethylene glycol is manufactured from ethylene through ethylene oxide which is the intermediate. The boiling point that i observed was actually the not the boiling point of the liquid but the temperature of the vapor at the tip of the thermometer however, it is known that the boiling point of a 10-20% ethanol / water mixture is around 85 c, somewhere between the boiling points of the two pure liquids. The purpose of this experiment was to determine whether or not salt would affect the boiling point of water much of the research i conducted rejected my hypothesis which stated: if i add salt to water, then the boiling point of the water will decrease.
Does salt effect the boiling temperature of water by jason project design plan water freezes at 32°f and boils at 212 °f dissolved substances such as salt lower the freezing point of water. Since cyclohexane’s boiling point is a higher temperature of in that would do the in thaw before the cyclohexane reached its boiling point and when cyclohexane was at its boiling point the in would hold been runing for the past 10 temperatures before cyclohexane.

Written by webadmin on august 25, 2015posted in uncategorized effect of salt on the boiling temperature of water many people assume that the laws of physics are set in stone when it comes to the freezing point or boiling point of water, everybody who has ever studied a little bit of science would be able to say water freezes at 32 degrees fahrenheit and water boils at 212 degrees fahrenheit. The main difference between boiling point and melting point is that the melting point is defined as the temperature at which solid and liquid phases are in equilibrium, whereas the boiling point is the temperature at which the vapour pressure of a liquid is equal to the external pressure. Boiling point, temperature at which a substance changes its state from liquid to gas a stricter definition of boiling point is the temperature at which the liquid and vapor (gas) phases of a substance can exist in equilibrium when heat is applied to a liquid, the temperature of the liquid rises. Basically, water is known as a solvent and salt is known as a non-volatile solute when you add salt to water, it makes water become an impure solvent and raises its boiling point above that of the pure solvent (action donation services, 2006.

Boiling point lift occurs when the boiling point of a solution becomes higher than the boiling point of a pure dissolver ( helmenstine 2012 ) basically h2o is known as a dissolver and salt is known as a non-volatile solute. The boiling point of a substance is the temperature at which the liquid boils this is the temperature at which the vapor pressure of the liquid is the same as that of the atmosphere when the boiling point is reached the chemical changes from the liquid to the gas or vapor phase.
