Why Does Salt Increase The Boiling Point Of Water
Camila Farah
Adding salt will also increase the boiling point but only slightly.
It occurs any time you add a non volatile solute such as salt to a solvent e g. For example in denver colorado the boiling point is about 95 c or 203 f. For saltwater the boiling point is raised and the melting point is lowered. The property isn t exclusive to water.
The temperature will increase about a one half degree celsius for every 58 grams of dissolved salt per kilogram of water. 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. The easiest way to increase the boiling point of water is to boil it inside a pressure cooker. At at high altitudes the lower pressure makes the boiling point several degrees lower.
If you add salt to water you lower its freezing point as well as raise its boiling point. Another way of putting the answer is to say that if the solute stays in the liquid there is less room for it to find various different states as the liquid boils away. If you add salt to water you increase its boiling point. It s 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.

The more salt or any solute added to water the more you raise the boiling point. I ll assume the salt is sodium chloride nacl table salt. But how does it work. This gives salt water a higher boiling.
