Why are chlorides used in flame test? | Socratic

21/6/2016· 1. Metal chlorides are usually more volatile than other salts. More of the salt will be converted to vapour in the flame and therefore give a brighter colour. 2. Chlorine atoms do not emit energy in the visible region. In the flame test, electrons in both the metal atoms and the chlorine atoms are excited to higher energy levels.
