How to Do a Flame Test for Qualitative Analysis

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. Every element has a signature emission spectrum that can be used to differentiate between one element and another.

Flame Test Colors: Photo Gallery - ThoughtCo

The flame test is a fun and useful analytical technique to help you identify the chemical composition of a sample based on the way it changes the color of a flame. However, interpreting your results can be tricky if you don''t have a reference. There are many shades of green, red, and blue, usually described with color names you wouldn''t find on even a large crayon box!

Potassium (K) and water - Lenntech

Potassium salts and mixtures of magnesium and calcium compounds are also applied regularly. Regeneration releases wastewater that is hazardous when discharged on surface water, and that is difficult to purify. Potassium is applied in glass production to make it stronger and solid. This glass is mainly applied in television screens.

Alkaline earth metal - Wikipedia

2019-5-6 · The alkaline earth metals are all silver-colored and soft, and have relatively low densities, melting points, and boiling points. In chemical terms, all of the alkaline earth metals react with the halogens to form the alkaline earth metal halides, all of which are ionic crystalline compounds (except for beryllium chloride, which is covalent).

Potassium CAS#: 7440-09-7
