It's important to note that the color observed in a flame test can be influenced by factors like:

* Concentration of the compound: Higher concentrations can lead to a brighter, more intense color.

* Presence of other metals: If the sample contains other metals, their characteristic colors might interfere or combine with the yellow of Iron (III) chloride.

However, in general, a flame test with FeCl₃ will exhibit a distinct yellow hue.
