what is the color of the flame of metal salts

When burning a salt, how do we know the flame color …

When burning a salt, how do we know the flame color comes from the metal ion and not the non-metal ion? I did a lab on this by burning different salts and observing the different flame colours.

Why do different elements make different color …

Different elements have different flame colours because their electrons have different allowed energy levels. > The Bohr model says that electrons exist only at certain allowed energy levels. When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy.

experimental chemistry - Why flame color of salts is

2019-3-19 · If a pure metal is heated up in a flame, we see it giving the flame a characteristic color, e.g. $\ce{Na}$ burns yellow. If a salt, e.g. $\ce{NaCl}$ or $\ce{Na2SO4}$, is heated up, resulting color to a greater degree still is that of the pure metal. Although the color does change depending on the anion, this effect is usually not much pronounced.

Creating Flame Colors - The Science Company

Project 2: Flame Color Tests Using Metal Salts. You can create a variety of colored flames by burning a small amount of different metal salts in a fire. In the lab, use a Bunsen burner or propane torch. The Procedure. Some metals will burn with a characteristic flame color.

Flame Tests Using Improvised Alcohol Burners - …

1999-7-1 · In this demonstration, an improvised alcohol burner, with a methanol solution of a salt as fuel, produces a long-lasting brightly colored flame. A disadvantage when using a regular alcohol burner is that the burner has to be cleaned and a wick replaced, before a solution of a different salt can be used. For our demonstration, alcohol burners are made from small (5-mL) glass vials.

Flame Tests and Emission Spectra - dec.ny.gov

2016-1-29 · Flame Tests and Emission Spectra . Teacher Background Information: Traditionally, flame emission spectra labs use solutions of toxic metal salts in Bunsen burners. Even when used on microscale the metal ions in the salt solutions become volatized. Additionally, the traditional protocol is not thermodynamically favorable.

What color does copper burn in fire? - Quora

What you probably mean is copper salts, which are used to color flames. There are two commonly used flammable copper salts and they produce different colors. Cupric chloride burns blue. Cupric sulphide burns green. There are other metal salts that burn other colors as well, for instance Potassium chloride burns purple. You can find a table here.
