Fluorine Displacing Chlorine from Sodium Chloride

F2 + 2NaCl → 2NaF + Cl2

概述

Fluorine, the most reactive element, displaces chlorine from sodium chloride to form sodium fluoride and chlorine gas. Fluorine is so reactive that it can even displace oxygen from water. This reaction occurs violently and must be handled with extreme care due to fluorine's extreme toxicity and reactivity.
