Flame Test
It is an important test for systematic analysis of cations as the 5th group cations show characteristic colour when exposed to flame in this experiment. These ions in their chloride form can impart heat energy which is released in the form of light energy when exposed to non-luminous flame. The reason various ions exhibit different colours is due to the reason that every metal ion has a different level of light energy.
Procedure-
-
Put some concentrated HCl on a watch glass.
-
Take the platinum wire and dip it in the Concentrated HCl solution and heat it by putting on the flame.
-
You will have to repeat this step unless the platinum wire shows any colour in the flame.
-
Subsequently, dip it in the solution of concentrated HCl followed by dipping in salt. Observe the colour it imparts in the flame.
