How are flame tests used in forensic science?
Flame tests are used to help identify substances used in murders
Why do scientists use flame tests?
To Determine the emission spectrum of a sample
What color does lead burn?
Lead burns with a bluish-white flame when ignited. Flame tests use analysis of flame color to detect the presence of particular elements within a compound.
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.
Several of the flame tests were shades of red What should be done in the laboratory to correctly identify one of these ions?
you will have to do another flame test to record the differences

What is the flame color of Lead II Nitrate?
Lead compounds tend to be blue in flame tests
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
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.
What is the method identifying metal?
there are many tests but flame test, colour and spectroscopy..are the prilimnary tests for identifying metals.
Why do scientists use flame tests?

What tests could be done to determine the identity of zinc?
flame test
What can happen when flame tests are carried out carelessly?
The results may be erroneous.
Why does the anion not play a role in the color of a flame in a flame test?
Anions do not play a role in the color of a flame in a flame test because they are not visible as the energy gap do not correspond to that of a visible photon. Flame tests are only applicable to cations.
