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.
With the flame test we can identify some chemical elements; see the link to Wikipedia, for ex.
The color of the flame test is specific for some metals. See the link below.
The HCl converts any contaminated impurities to the corresponding chlorides, which are more volatile and easily vaporized. That way, they are vaporized more easily and quickly in that flame, allowing the cation to create the correct color flame without contamination.
to identify an unknown sample by its emission spectrum
You can use a technique called flame test where the substance is heated in a flame. The cations present in the substance will emit distinct colors of light based on their unique electronic configurations. By comparing the observed color with a reference chart of known cation emissions, you can identify the cations present in the substance.

The color of the flame is indicative of the constituent elements.

Iron (III) chloride does not produce a distinct color flame during a flame test. This compound is typically used more for other chemical tests rather than flame tests for cation identification.
1. not all elements give colour to the flame 2. flame test is not always accurate

Testing for cations is a test used in chemistry to identify metal or metal ions (cations) found in compounds. ... This test uses sodium hydroxide or aqueous ammonia to test and identify metal ions by the precipitation formed.
