Title: Why doesn't chlorine from salt dissolved in water boil away?
Post by: AllAmericanBreakfast on November 04, 2018, 05:36:05 PM

The boiling point of chlorine is -100 degrees Celsius. When NaCl dissolves in water, the individual Na and Cl particles separate and mix with the water. Since Cl has such a low boiling point, why doesn't it immediately escape into the atmosphere as a gas on contact with water, leaving a pot full of pure sodium when all the water has finished boiling off?

Sodium chloride doesn't contain free chlorine.
