At the concentrations typically used in food, it increases the boiling point.”

When salt is added, the boiling point rises by a few degrees.

The more salt added, the higher the boiling point.

This is why, for example, seawater takes longer to heat up and boil than pure water."

Does Altitude Impact Boiling Point?

Water boils faster at higher altitudes, with a boiling point of 208F instead of 212F.
