Flame Test Of Chemicals Lab Investigation (Product Code: SLE/CH/133) is a classroom investigation, sized for a class of 40 students, in which learners discover how elements can be identified by the colour they give to a flame. Students observe and record the colours emitted by metallic elements on heating, compare them with known standards to identify unknown samples, and use the results to explore the electronic structure of the atom. Supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, it serves as a ready-to-run flame test kit for schools in India teaching atomic structure and qualitative analysis.

When a metal compound is heated in a hot, non-luminous flame, some of its electrons absorb energy and jump to higher energy levels; as they fall back they release light of particular wavelengths, which the eye sees as a characteristic colour. Sodium compounds, for instance, give an intense yellow-orange flame. Students first test the known standards and build a colour reference table, then use that table to name the unknowns, and finally discuss why a red flame corresponds to lower-energy light than a violet one.
Clean the sampling loop or splint thoroughly between samples, because a trace of sodium can mask fainter colours, and let students view the flames against a dark background. Viewing the same flames through a spectroscope turns a colour observation into a set of spectral lines, which is an effective extension for senior classes. Teachers looking for a chemistry teaching kit in India that connects practical work to atomic theory will find this investigation covers both in a single session.
This lab investigation is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, India, a supplier of practical kits and apparatus to schools and colleges. Visit our company profile to learn more.

How many students is it designed for?
A class size of 40 students.
What will students learn?
How elements can be identified using flames, how flame colour relates to the electronic structure of the atom, and how colour relates to energy in the electromagnetic spectrum.
What exactly is in the kit?
The component list is not detailed on this page. Request it through our contact page so you can check what your laboratory needs to add.
Do we need a burner?
A hot, non-luminous flame is required, usually from a Bunsen burner. If your laboratory does not have enough burners, we can quote them with the kit.
Why do some colours look alike?
Faint colours can be hidden by sodium contamination or confused by eye. Careful cleaning between samples and a spectroscope both help students tell similar flames apart.
What safety precautions apply?
Goggles, tied-back hair, a clear bench and supervision near open flames. Allow hot loops or splints to cool before handling.
Can you supply several classes or export orders?
Yes. We supply institutions in India and international markets; include code SLE/CH/133 and the number of kits you need.
Ask for pricing on the flame test investigation through the contact page, or add it to the enquiry cart along with burners and goggles.
