What electromagnetic waves does a fire give off?
IR, Red, Orange in a typical fire. A pure hydrogen fire however gives off only IR and a barely visible amount of Blue. Metallic salts in the flame will add their own characteristic colors (e.g. sodium: Yellow, copper: Green).
Why is the flame test for metallic ions?
When an electron jumps from an energy level that is farther away from the nucleus to an energy level that is closer to the nucleus the electron gives off energy. When doing a flame test this energy is in the form of a color change. One can identify the change based off of the color.
What is happening in flame test lab?
Due to electron transitions in atoms some chemical elements emit a characteristic colored flame.
Why not all metals emit colors in the flame test?
no not all metals produce a colour flame.
What flame is produced when charcoal is sprayed into the flame?
Sprinkling charcoal in a flame will cause the flame to change colors. This is apparent in fireworks displays, which routinely use charcoal.
Is an element's flame color a chemical characteristic?
The color of the light emitted by an element heated within a flame is a physical characteristic, but this particular physical characteristic is itself determined by a chemical characteristic: the distribution of electron energy levels within the element.
How is a Bunsen burner used to identify a substance?
The role of Bunsen burner is to heat; some metallic ions have specific colors in the flame.
What electromagnetic waves does a fire give off?
IR, Red, Orange in a typical fire. A pure hydrogen fire however gives off only IR and a barely visible amount of Blue. Metallic salts in the flame will add their own characteristic colors (e.g. sodium: Yellow, copper: Green).
What type of flame is characteristic of incomplete combustion?
white flame

Why do fires burn certain colors and not others?
This depends on many things,2 of them are the tempreature of which your particular fire is burning by. Another thing which effects the colour of a flame is when you burn certain chemicals in a fire to perform flame tests. For example when a flame test is performed on Strontium(Sr2+)a scarlet red flame can be observed.
Is flame coloration a test for the metallic ion or for the nitrate ion?
flame coloration is a test for the Metallic ion because the metallic ions will enter an exited state and release photons energy, in the form of light, as they return to their ground state.
What difficulties may be encountered in the use of the flame test for identification of metallic ion?
A difficulty that may be found in using the flame test is eye imperfection. Another is subjectivity when it comes to perceiving the colors.
What color flames do you get when you burn aluminum?
when aluminium sulphur is burnt in a blue flame the flame will turn to an orange flame
What is happening in flame test lab?

Why does barium make flames green?
It is the characteristic colour of a barium flame.
Does a candle flame show any of characteristic of life?
yes it does. energy
