Why are chlorides used in flame test? | Socratic

21/06/2016· There are two reasons why chlorides are used in flame tests. > 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.

Flame Test: Why does the flame colour of calcium …

15/07/2019· The typical flame temperature is not hot enough to cause atomic excitation and completely break calcium compounds into calcium atoms. If this were true you would see a violet flame (422 nm) after introducing calcium. We see reddish color which is always contaminated with sodium''s yellow color.

Determining the Metal Elements in Compounds …

09/02/2017· For example, calcium and Unknown A had the same color photons released, showing an equal amount of energy released as well. Placing calcium chloride over the flame released the same amount of energy as Unknown A, so the electrons in the metal elements of Unknown A and calcium chloride must exist at the same energy levels.
