hi, the metal salts used in the flame tests are the same as those used to make fireworks. when the metal salt is heated the electrons get excited and jump to a higher level. As they get less excited they drop back down a level and the energy they lose is lost as light. This is what we see as the colour.
What else can I help you with?
What are some practical uses for flame colours of certain metals?
Flame tests using certain metals can be used in chemistry to identify unknown substances based on the characteristic colors emitted when in contact with a flame. This is useful in forensic analysis, safety inspections, and chemical education. Additionally, flame colors can be used in pyrotechnics for creating colorful fireworks displays.
What substance turns red in flame tests?
Lithium turns red in flame tests.
What color does beryllium produce in fireworks?
to the best of my knowledge beryllium is not used in pyrotechnics at all it is quite hideously toxic, and it is one of those metals that imparts no particular coloration that is visible to the naked eye in flame/fluorescence tests
How do impurities affect the outcome of the flame tests?
The result can be erroneous.
When doing flame tests Li Cl and K Cl both contain Cl so what makes the flame tests different colors?
The flame tests are different because they contain different metal cations. Since the metals were the variable that you changed, you know that can be the only reason why the flames would be different colors.
Flame tests in daily life?
Fireworks

Uses of flame tests in industry?
There are a few different applications of a flame test. These applications include testing for specific chemicals, checking some items specifically for poisonous chemicals, and testing fireworks.
What substance turns red in flame tests?
Lithium turns red in flame tests.
Why use flame tests in forensic science?
Flame tests allow you to get some idea of what substances make up a given sample. It is particularly useful for the identification of polymers, because many of them give off unique burn patterns.

What are the techniques used to analyze inorganic chemicals?
Precipitation tests Flame tests Tests on gases Other ions
What color is produced by sodium compounds in flame tests?
The color that is produced is orange
When sodium is heated in flame it will give?
Flame tests are often used to identify metals and other substances, such as sodium. If you expose the element sodium to flame, it will give off a bright, vibrant yellow color.
What color does Iron (III) chloride turn in flame test?
Iron (III) chloride does not produce a distinct color flame during a flame test. This compound is typically used more for other chemical tests rather than flame tests for cation identification.
How do impurities affect the outcome of the flame tests?
The result can be erroneous.
Why can you not use flame tests to identify all the elements?
1. not all elements give colour to the flame 2. flame test is not always accurate
