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

Why doesn''t magnesium chloride produce a flame color, when subjected to a flame …
2008/2/2· The flame test colors are usually not the same as those produced when the element itself burns, BTW, and have nothing at all to do with the color of the element itself. For example, magnesium is a silvery white metal.
Chlorides | AMERICAN ELEMENTS
Chlorides are compounds that contain chlorine along with a more electropositive element. The chloride form of any metal is generally soluble in water, with the exception of lead chloride, which is only slightly soluble, and silver chloride, which is insoluble. Antimony chloride, bismuth chlorides, and others decompose in water to create oxychlorides. Most metal chlorides can be melted without
Observe the color of the flame. Allow only half of the wood splint to burn. Extinguish the wooden splint by placing it in your rinse beaker. Record your observations for the flame color by the metal chloride in the Data Table. Repeat steps 7-10 for the other metal
Determination of sodium and potassium by flame photometry
When a solution containing ions of sodium and potassium is spayed into flame, the solvent evaporates and ions are converted into atomic state. In the heat of the flame (temperature about 1800ºC), small fraction of the atoms is excited. Relaxation of the

Just as a fingerprint is unique to each person, the color of light emitted by an element heated in a flame is also unique to each element. In this experiment, the characteristic color of light emitted by calcium, copper, lithium, potassium, sodium, and strontium ions will be observed.
Note: Due to the vivid and persistent colored flame produced by the sodium chloride, the flame color of sodium should be demonstrated last. When flame colors become less vivid and take on a yellowish tinge, it is time to dry them in an oven overnight.
