How does sugar affect the boiling point of water?

Adding sugar to water increases the boiling point. Adding 1 gram of sugar, or any other substance that does not create ions, increases the boiling point of a liter of water by 0.94 degrees Fahrenheit above its normal 212 degrees Fahrenheit.

The formula for calculating the effect of sugar and other non-ionizing solutes on the boiling point of water is linear, which means that every additional gram has the same effect on the boiling point of a liter of water. Ionizing solutes, such as salt, impact the boiling point of water much more significantly; in the case of salt, that same gram elevates the boiling point of a liter of water by 1.87 degrees Fahrenheit.
