color of the flame metal calcium chloride in andorra
This page describes how to perform a flame test for a range of metal ions, and briefly discusses how the flame color arises. CuCl2 Hydrochloric acid Nitric acid Ethanol: 8. Copper II (cupric) chloride has the chemical formula CuCl2.
The metal has a silvery color, is rather hard, and is prepared by electrolysis of the fused chloride to which calcium fluoride is added to lower the melting point. Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame, forming largely the nitride.

The chemical compound potassium chloride is a metal halide salt composed of potassium and chloride. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water and its solutions have a salt-like taste.
Determination of Calcium Ion Concentration
calcium ions changing colour from blue to pink/red in the process, but the dye–metal ion complex is less stable than the EDTA–metal ion complex. As a result, when the calcium ion–PR complex is titrated with EDTA the Ca2+ ions react to form a stronger
Flame Tests – Identifying Metal Ions
Group 2 metals are known as the alkaline earth metals and include beryllium, barium, magnesium, calcium and strontium. Both groups one and two metals have a distinct flame color which allows us to identify the presence of a metal ion in a solid sample.
Colored flames - MEL Chemistry
Scarlet flame – lithium chloride It’s worth noting that the flame’s color depends on the metal ion; the salt’s anion has practically no influence whatsoever. This characteristic of certain metals is also exploited to produce colored lights — in pyrotechnics, for instance.

Ferric Chloride: Clearing the STUFF Out of Water
Ferric chloride (FeCl3) is a chemical compound consisting of two elements--iron (Fe) and chlorine (Cl). "Fe" comes from the Latin word for iron which is ferrum. The small "3" next to Cl in the chemical formula means that for every atom of iron, there are three atoms
Aluminum.This is the metallic base of alumina, which is the plastic principle of certain kinds of clay. The color of aluminum is white, inclining to blue; it is very malleable, and ductile. Its specific gravity is only about 2.60; its melting point not less than 1000 Fahr.

To cleanse the flame, spray a fine mist of distilled water until the previous flame color is no longer present. Repeat steps 2-4 for each of the remaining metallic salt solutions. After viewing the flame colors produced by MgCl2, NaCl, and KCl with the naked eye, view the flame colors through a …
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.

If you use a pure metal powder and observe a color spectrum, it is clearly due to the metal atoms as there is nothing else. The question that you are asking comes into play when you use a metallic salt, which upon heating disassociates into metal ions and nonmetalic anion atoms or groups.
