How are flame tests used in forensic science?
Flame tests are used to help identify substances used in murders
Why in flame tests concentrated hydrochloric acid is used to make the paste of the salt?
Hcl liberates the ions of the salt which enables it to impart colour to flame easily.
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.
Why glass rods are used for flame tests in inorganic qualitative analysis?
It is not used in organic analysis due to the imparting of yellow color to the flame by silicates in the glass rod.
What metal burns with a blue flame?
In qualitative analysis, flame tests are used in confirming what kind of metal is present in a solution. The green flame or bluish-green flame color is usually present whenever copper metal is present in a solution.

What is the flame color of Lead II Nitrate?
Lead compounds tend to be blue in flame tests
Why are flame tests useful when making fireworks?
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 is FT1 on electrical cable?
FT1 is one of three vertical flame tests. FT1 cables can be used in buildings that are rated combustible. For more information search you browser for Flame Test ratings
Why glass rods are used for flame tests in inorganic qualitative analysis?
It is not used in organic analysis due to the imparting of yellow color to the flame by silicates in the glass rod.
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
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.
