## What happens when you add salt to water?

Updated June 28, 2019. If you add salt to water, you increase its boiling point. The temperature will increase about a one-half degree Celsius for every 58 grams of dissolved salt per kilogram of water.

### Why does adding salt increase the boiling point of water?

The more salt (or any solute) added to water, the more you raise the boiling point. The phenomenon depends on the number of particles formed in the solution. Freezing point depression is another colligative property that works the same way, so if you add salt to water you lower its freezing point as well as raise its boiling point.

How does salt affect the amount of CO2 that can diffuse into water?

Good question. Salt does affect the rate at which CO2 can go into water by affecting its solubility. The higher the level of salt, the lower the solubility. Because of this, you might expect that lakes would have a higher level of CO2 (per unit volume) in the water than the ocean, but this is actually quite a complex question.

## How much salt would one need to add 1 kg water to change?

In reality, you would need to add 230 grams of table salt to a liter of water just to raise the boiling point by 2° C. That is 58 grams per half degree Celsius for each liter or kilogram of water. That is much more salt than anyone would care to have in their food.

### What happens when you add salt to ice cream?

When salt is added to the ice bath (usually rock salt in ice cream making), it comes into contact with the thin layer of water on the surface of the melting ice. The salt dissolves and the water becomes salty.
