Adding Salt To Water Raises Boiling Point. So a big spoon of salt in a pot of water will increase the boiling point by four hundredths of a degree. If you add salt to water you increase its boiling point.
Its true that part of why salt dissolves well in water is that it falls apart into charged particles but some uncharged molecules also dissolve in water and also raise the boiling point. So a big spoon of salt in a pot of water will increase the boiling point by four hundredths of a degree. For every tablespoon of salt added the boiling temperature increased by almost 3 degrees.
Therefore my hypothesis was not supported the more salt that is added to water the higher the boiling.
Although adding salt to water raises its boiling point its worth noting the salted water actually boils more quickly. Whenever a solute such as salt is added to a solvent such as water the boiling point becomes higher than that of the pure solvent. Adding an ionic salt to water makes the water boil faster. That seems counter-intuitive but you can easily test it yourself.
