How does a flame test work in chemistry?
Flame Tests: A Favorite Chemistry Lab. The test involves heating a sample of the element and observing the resulting color of the flame. When atoms of elements are heated to high temperatures, some electrons may absorb enough energy to allow them to move to higher energy levels. The element is then said to be in the "excited state".
How is the color of a Flame recorded?
One of the samples was put on the spatula and the formula of the salt solution was recorded into Table 1. The spatula with the salt solution was put over the flame. The color of the flame was recorded in table 1.
Why does a flame test look like a bar code?
When looking at the spectrum of light emitted from a fluorescent lamp, sodium lamp, neon sign, or flame test, only distinct wavelengths of light appear. The observed spectrum looks like a bar code. Line spectra are well observed in lean conditions because the atoms must emit their own light without interfering with each other.
Why do you need a flame test for fireworks?
Flame tests can also be used to find the color of fireworks one wants to use. By using the metal that emits the color one wants in fireworks, one can get the desired color. This experiment will be conducted using the same spatula, the same Bunsen burner, the same kind of acid and nitrate bonded to every one of the metals.
