Flame AAS - Chemical Instrumentation

Flame Atomic Absorption is a very common technique for detecting metals present in samples. The technique is based on the principle that ground state metals absorb light at a specific wavelength. Metal ions in a solution are converted to atomic state by means of a flame.

The salt of an alkali metal gives violet colour in the

The salt gives violet colour in the flame test, which shows the presence of potassium ion (K +) in it. Further, the aqueous solution of salt gives white precipitate with B a C l 2 in acidic medium, so it must contain sulphate ion (S O 4 2 − ) and the precipitate is of B a S O 4 . Thus, the salt is K 2 S O 4 .

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.

Does a metal or nonmetal ion determine the burn color?

The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light.

Flame Test | Explanation, Definition, Information & Summary

14/10/2019· Primarily, the flame test detects the presence of metal ions in a compound, and as ions of each element have a specific characteristic based in their emission spectrum, the flame test for every element is different and distinctive. This distinction is shown by the color of flames given out when the salt containing certain metal ions is burnt.

The Flame Test, a Safer Version of the Rainbow Demonstration

The Flame Test is a safer version of the traditional Rainbow Demonstration, an exercise popularly conducted in chemistry classrooms.The purpose of The Flame Test is to demonstrate to students the variety of colors produced when different metals or salts meet a flame.

Colored Fire Flames

Color the flames of your campfire. This is just the site I was looking for. When I was young we used to get pine cones (lived where they were plentiful) and some places you could buy these that were filled with paraffin which had been impregnated with copper salts to make the flame blue and green.
