Why are chlorides used in flame test? | Socratic
2016/6/21· 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
2019/12/17· There are three basic flame types: neutral (balanced), excess acetylene (carburizing), and excess oxygen (oxidizing) as shown below. A neutral flame is named neutral since in most cases will have no chemical effect on the metal being welded. A carburizing flame will produce iron carbide, causing a chemical change in steel and iron.
