Iron DOES react to a flame test. According to the "handbook for prospectors and operators of small mines" the effect of oxy-gas flame on iron is: "ignites.sparkles;dark oxides". Are you certain that you are performing the test correctly ?
Iron chloride does not produce a distinctive color in a flame test. It typically appears as a pale yellow-green flame due to the presence of the chloride ion rather than the iron ion.
Cobalt gives a blue flame test while chromium gives a green flame test.
Sodium hydroxide does not produce a distinct color in a flame test. It is the sodium ions that give a bright, persistent yellow color to the flame.
Sodium ions give a bright yellow flame color during a flame test.
well , the colour of potassium chloride is a lilac colour :) hope this helps
Iron has a yellow-gold color in the flame test.
Iron chloride does not produce a distinctive color in a flame test. It typically appears as a pale yellow-green flame due to the presence of the chloride ion rather than the iron ion.
It is not the anions (e.g. iodide) that are responsible for the flame test color, rather the cations such as sodium ion, potassium ion and calcium ion give you different colors.
Its like Mg, it has no colour. So bright light
Cobalt gives a blue flame test while chromium gives a green flame test.
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.
Sodium hydroxide does not produce a distinct color in a flame test. It is the sodium ions that give a bright, persistent yellow color to the flame.
All sodium salts will give a yellow flame test, because of the metal sodium in the compounds.
Sodium ions give a bright yellow flame color during a flame test.
Selenium nitrate typically gives a pink or reddish flame color when subjected to a flame test.
The color of the flame test is specific for some metals. See the link below.
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
