It is not suffiecient to identify a cation only on a flame test.æ You must also identify the color of the flame which corresponds to a certain element.
This is a spectrometer.
Some flame colours are characteristic of metals present, eg Lilac for K+, Red for strontium. However, this is only indicative, because there are a few at least that have a red colour, so it needs to be proven further with a chemical test
The flame test is not used to detect magnesium; a magnesium oxide rod is used as a support for the solutions of other elements in the flame test.

to identify atoms present on an element
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.

In a flame test, the color of the flame produced can be used to identify the presence of certain elements in a compound. This is due to the unique way each element emits light when heated. By observing and comparing the color of the flame with known standards, one can draw conclusions about the elements present in the sample being tested.
A flame test is a qualitative analysis technique used to identify the presence of specific elements based on the color of the flame produced. It is not typically used for quantifying the amount of the element present in a sample.
Yes. Every element has a very particular emission spectrum. Each element has a specific structure of nucleus and electron orbits. Because of this, when a certain element is ionized (ie. by a flame), the electrons rejoining with the nuclei give off a specific frequency of light. The color of light witnessed after burning the compound is an indicator of the elements present.

The element used in an oxy-acetylene flame is carbon. Acetylene gas acts as the fuel, while oxygen is used as the oxidizer in the flame. The high temperature resulting from the combustion of acetylene and oxygen produces a clean and precise flame that is commonly used in cutting and welding applications.
