WebJan 8, 2024 · In chemistry, the flame test is a simple qualitative analysis technique to check for the presence of alkali, alkaline-earth metal ions and some transition metals. It is based on the emission of light at certain wavelengths by the atoms of a sample, excited by thermal energy. A small amount of sample – or a solution of it in hydrochloric acid ... WebThe flame test produced a lighter orange flame indicating there was not a combustion reaction (shown in Table 2). The colour pink indicates that the cation Cobalt (Co2+) is present in a solution. Since the solution A was originally observed as a pink, transparent liquid, it was determined that the Cobalt was present in solution A.

A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic flame emission spectrum (which may be affected by the presence of chloride ion). The color of flames in general also depends on temperature and oxygen fed; see flame color. WebToday, I will give you an overview of this common experiment that you might do in your chemistry class. To understand the flame test, you need to know about the electromagnetic spectrum. Light has a dual nature; it is made up of both particles and waves. This was proved by Thomas Young’s double-slit experiment that he performed in 1801.

WebHow Does The Flame Test Work? The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner.
